    Why Max is different

    Most arch support insoles are too soft. Step on them and the arch flattens, so by mid-shift you're back where you started.

    Max is built to be stood on. A high-rise arch platform (1.38" / 3.5 cm) on a firm base stays lifted for 8, 10, or 12 hours. A deep heel cup keeps your heel centered so your foot stops rolling inward.

    Firm is the feature. It's what lets you finish the day on your feet.

    Real customers confirm it

    The Science

    Plantar fasciitis: Harvard Medical School: proper arch support distributes pressure evenly across the foot, reducing strain on the plantar fascia. Harvard Health Publishing

    Flat feet: In a 2025 study, arch-support insoles reduced lower-leg and thigh muscle fatigue in people with flat feet while walking, compared with flat insoles. Scientific Reports, 2025

    Long hours on your feet: A review of 26 studies: insoles built for all-day standing improve comfort and reduce fatigue. Safety and Health at Work, 2026

    Bunions: Stanford Health Care lists arch supports among the first non-surgical steps for bunions: they redistribute your weight as you walk and take pressure off the big toe joint. Stanford Health Care

    Your feet are the foundation. When they collapse, everything above them follows.

    Feet screaming by 2pm? Your arch is collapsing.

    A collapsed arch rolls your foot inward on every step. The strain moves up: ankle, knee, hip, lower back.

    Sound familiar?

    • By mid-shift, all your weight sits on your heels.
    • Ball, tape, ice. Helps for an hour.
    • No more runs or long walks.
    • You've started to think this is just getting older.

    It isn't age. It's your arch. Max holds it up all day.

    Side view of a foot with a dropped arch and the plantar fascia pulling at the heel

    First step out of bed the worst? It starts in your arch.

    The band under your foot holds the arch up like a bowstring. When the arch drops, it pulls at the heel. All day. Overnight it tightens, and the first step pulls it again.

    • Hand on the wall on the way to the bathroom.
    • Stand up after sitting, and it's back.
    • Stretches, ice, the night splint. Helps for a morning.
    • You've stopped planning walks.

    It keeps coming back because the arch keeps dropping. Max holds it up, all day.

    High arch over a low insole, with a gap under the archTypical insole

    High arches? Your heel and ball of foot carry everything.

    Most insoles are built for an average arch. Under a high arch they leave a gap, so two small points take all your weight.

    • The "arch support" never touches your arch.
    • The "high arch" version goes flat in a month.
    • Heel, ball of the foot and outside edge ache by evening.
    • You've been told only custom works.

    Most brands don't print the arch height. Max's is 1.38" / 3.5 cm, on a base that doesn't give.

    X-ray of a foot with a bunion at the big toe joint

    Bunion aching by evening? Your big toe takes every push-off.

    When the arch drops, the foot rolls in. You push off the side of the big toe joint, thousands of times a day.

    • The joint aches and swells by the end of the day.
    • The bump rubs the side of every shoe.
    • Wider shoes help the rub. Not the ache.
    • You've been told surgery is the only fix.

    No insole changes a bunion's shape. Max holds the arch up, so less of your weight lands on that joint.

    Flat feet seen from behind, both ankles leaning inward

    Flat feet? That's why your knees, hips and back hurt.

    The arch drops, the ankle rolls in, the knee follows, the hip tilts. Your lower back pays for all of it.

    • A lot of walking or standing, and your hips and back start hurting.
    • Your ankles roll inward when you walk.
    • Soft insoles squish flat. Your feet still roll in.
    • Some days you walk like you're 90.

    It isn't age. It starts at the floor. Max holds the arch up under your full weight.

    Man at the end of a long shift rubbing the arch of his foot

    Feet burning by hour three? Your arch is collapsing.

    On concrete your arch never gets a break. A few hours in, the muscles tire and the arch drops. The burn, the limp and the sore back follow.

    • By hour three you're shifting from leg to leg.
    • You walk so slowly your boss notices.
    • Every insole you tried went flat in weeks.
    • You've done the math on how many more years you can do this.

    Max holds up to 330 lbs / 150 kg without flattening. Finish the shift like you started it.

    A soft insole arch folding flat next to a firm insole arch that holds

    One custom pair, moved from shoe to shoe every morning?

    Custom orthotics cost hundreds, and a second pair costs the same again. So you switch one pair between shoes. And the cheaper insoles you tried? The arch flattened under your weight.

    • You spent a fortune on customs. Some worked, some didn't.
    • You change them from shoe to shoe, every morning.
    • Other brands flattened out in a week or two.
    • Your customs wore out, and a new pair costs hundreds again.

    Customers say Max is as good as their customs, or better, at a fraction of the price. So you can keep a pair in every shoe.

    Which condition are you dealing with?

    Pick yours to see how Max helps.

    • High-rise arch, 1.38" / 3.5 cm

      Gives flat feet the arch they are missing. It is firm, so it does not flatten when you stand on it.

    • Deep heel cup

      Stops the heel from rolling inward. That roll is what tilts your ankles and knees.

    • Holds 330 lbs / 150 kg

      The firm base keeps the arch up all day, not just for the first hour.

    5 stars

    I was honestly surprised by how comfortable these felt from the moment I put my work boots on. Having flat feet my whole life, I was expecting some arch pain or cramping while my feet adjusted, but after the first couple of days, I was amazed at the difference. They’ve made my work boots noticeably more comfortable and supportive, and I’ll definitely be buying another pair for my other shoes. Wish I’d tried them sooner!

    • Arch that fills the gap

      A high arch leaves a gap under your foot, so the heel and the ball carry everything. Max fills the gap and shares the load.

    • Heel pad

      A high, stiff arch does not absorb shock. The heel pad does it for you.

    • Ball-of-foot padding

      Takes pressure off the ball of the foot, where high arches press hardest.

    Thierry T, USTrustpilot
    5 stars

    I have high arch feet and those insoles are great. I’m on my feet all day long. My feet don’t hurt anymore at the end of my shift. Thank you OrthoFlexx. I will buy some more in the next few weeks.

    • Firm arch support

      Holds the arch up, so the band under your foot is pulled less with every step.

    • Heel pad

      Softens each heel strike, where the pain is sharpest.

    • Deep heel cup

      Keeps the heel in place, so the sore spot is not pushed around inside the shoe.

    Thomas L, USTrustpilot
    5 stars

    I have tried every orthotic including very expensive custom insoles from the podiatrist and nothing ever worked for plantar fasciitis. This is the first ones that actually worked for me. I have been pain free for 3 months. The first time in years. I would highly recommend for people with high arch plantar fasciitis.

    • Firm arch support

      A dropped arch rolls the foot inward and loads the big toe joint. Max holds the arch up, so the joint takes less pressure.

    • Ball-of-foot padding

      Padding right behind the big toe joint, where the bump takes the most pressure.

    • Full length, trim to fit

      Trim it to your shoe's own insert, so the front of your foot is not squeezed.

    Maro, CATrustpilot
    5 stars

    My soles felt balanced like weight is distributed less at the front part on the bunions. After wearing them all day at work standing, I finished the day with no pain in my bunions. Definitely impressed.

    • Alignment from the ground up

      A collapsed arch tilts your ankles, knees and hips. Max keeps them in line while you wear it.

    • Holds 330 lbs / 150 kg

      Does not flatten by mid-shift, so the alignment holds all day, not just in the morning.

    • Cushioning layers

      Absorbs the shock of hard floors before it travels up to your back.

    Cory F, USTrustpilot
    5 stars

    Best insoles I have ever used. I work 10-12 hours standing on concrete, and not only have they improved the pain in my feet significantly, my back and knee pain have improved as well.

    How the Tri Support System™ works

    Three parts. One job: support that lasts all day.

    OrthoFlexx Max structure: firm arch support, U-shaped heel cup and cushioning layers
    • Firm arch support

      1.38" / 3.5 cm of firm lift that doesn't flatten under your weight, even after a 12-hour shift.

    • U-shaped heel cup

      Keeps your heel centered so your foot stops rolling inward.

    • Cushioning layers

      Padding under the heel and the ball of the foot softens every step.

    What People Are Saying About OrthoFlexx

    • I have tried every orthotic including very expensive custom insoles from the podiatrist and nothing ever worked for plantar fasciitis. This is the first ones that actually worked for me. I have been pain free for 3 months. The first time in years.

      — Thomas L, US
    • Noticed a big difference the 2nd day after wearing them as there was no foot pain the second I got out of bed to walk, which hasn't happened in years.

      — Renee, CA
    • The podiatrist gave me some relief after several sessions, but it came back over time. Then I discovered Orthoflexx, to say I was suspect of their claims would be an understatement. However my concerns were unfounded. Within 5 days of wearing the Orthoflexx product my plantar fasciitis appeared to be gone. It is now a year that I have been wearing the inserts and my feet feel fantastic.

      — Frank B, AU
    • I tried all the over the counter orthotics and buckles, I got professional orthotics. It lasted a while and my pain returned. Then I needed to decide to purchase the professional orthotics again, $$$$, or give it one last shot on my own. I found these and I can't tell you how happy my feet have been.

      — Jennifer M, US
    • I had plantar fasciitis in my left foot which was quite severe. It took about 4-6 weeks for the pain to not only stop but it totally disappeared. I still can't believe it, I couldn't even touch my heel because of the pain but now it's back to normal.

      — Enrique C, AU
    • I struggle with shoes. Have a very high arch and even the 'brand names' that advertise arch support aren't nearly enough. These are the best inserts I have found!

      — Bena T, US
    • I have tried every orthotic including very expensive custom insoles from the podiatrist and nothing ever worked for plantar fasciitis. This is the first ones that actually worked for me. I would highly recommend for people with high arch plantar fasciitis.

      — Thomas L, US
    • What sold me on these insoles was the durability and strength of this product. These insoles maintain their shape and therefore their support of your foot and especially the arch. I have very high arches. Most insoles were just cushion not architectural support.

      — Michelly, US
    • Best insoles I have ever used. I have high arches and struggle to find an insole that provides stability and comfort.

      — Joe W, US
    • Having higher arches, I always had sore feet after a long day at work. After wearing them for about two months, I realized that my feet didn't hurt, but didn't wanna have to switch them between all of my shoes, so I committed to buying a couple of pairs.

      — Thomas M, CA
    • My soles felt balanced like weight is distributed less at the front part on the bunions. After wearing them all day at work standing, I finished the day with no pain in my bunions. Definitely impressed.

      — Maro, CA
    • These insoles have been a life saver! I have been suffering with bunion pain and mid-foot pain from fallen arches/overpronating for so long. They are so comfortable!

      — Stephanie G, US
    • They have really helped take the pressure off my bunions. I ordered a second pair so I don't have to keep switching from shoes to sneakers etc.

      — Melanie S, US
    • The insoles take a little time to get used to since they shift your weight in different areas of your foot. This has benefitted me as the pressure on my big toe isn't as great and my pain in that area has diminished by at least 50%.

      — Bill K, US
    • I have very flat feet and bunions, so I wanted good insoles to help alleviate the stress those conditions have on my feet. These give better support than the ones I got at the podiatrist's office.

      — Bridget S, US
    • I've been wearing orthotics for years but lately had pain in my foot and it had stopped me getting out to do my daily walks. Within a week of wearing the pain has gone. I have flat feet and was worried the higher arch may have caused more pain but it seems to have strengthened muscles in my foot.

      — John M, NZ
    • I already have had one knee replacement and the other feels overworked. I am celebrating my 80th birthday in 3 months and having discovered these insoles just made my year. Suddenly walking is so much easier and my body feels balanced.

      — Ursula J, CA
    • I have flat feet and arthritis knees. These insoles make me walk better and makes my knees feel better. Both my husband and my physiotherapist says I walk much better since I got these insoles.

      — Judi K, CA
    • I have flat feet, my feet hurt if I am doing a lot of walking or standing. I was doing a lot of walking and standing the other night and was honestly waiting for my hips and back to start bothering me and was surprised when they didn't. I've tried a lot of other products in the past. These actually work!

      — Jennifer G, US
    • I sell shoes for a living and these insoles are fantastic. My hips hurt less, my back barely hurts, and both area of my body have had surgery. Best insoles for these flat feet!

      — Drew M, US
    • I work 12 plus hours walking and standing on concrete floors. My heels would hurt by the time I was done. But the next morning the heels would be worse. They have been a life saver. My heels don't hurt after the long days working.

      — Jen R, US
    • I stand on them for 13 hours a day on hard concrete floors and my feet and calves aren't tight and sore by the end of the day. I'll certainly reorder.

      — George P, AU
    • My left foot is over pronated. I can stand for hours on concrete flooring and my foot isn't killing me when I get home from work now. I am so relieved.

      — Cilya F, US
    • I was having heel/ankle pain for months on one side. Also knee pain all the way up to hip. Stand on my feet at work for over 10 hours a day. Took a few days to get used to them. Heel pain is gone and other pains seem to be going away also.

      — Do, CA
    • I am on my feet all day and they always hurt and made me tired. After a few days of wearing orthoflex, my feet do not hurt nor does my back. It's nice to not feel so tired when I get home from work.

      — Robert H, US
    • Finally found orthos that work as well as my 10yr old rx orthos. And a lot cheaper. Next sale I'm going to stock up so I can put one in each pair instead of limping around the house trying to remember which shoes I left them in.

      — Ann O, US
    • I overpronate and have been reliant on orthotics for over 20 years. But orthoflexx are not only equally effective, they're cheap enough for me to have a pair in the shoes I wear all the time.

      — Christine E, AU
    • Best orthotics I've ever used. Even better than my custom orthotics from my podiatrists. The best aspect is that they hold up.

      — Joy G, US
    • I've had numerous pairs of custom orthotics. The last pair I purchased was $800. The orthoflex feels very similar and is built to last longer.

      — Robert S, JP
    • I have paid for custom orthotics over several years and find these to be equal to the custom result.

      — James G, AU
    • These work better than my custom $600.00 orthotics!

      — Jim G, US
    • Very sturdy arch support.

      These insoles have a very sturdy arch support that does not mushroom on a 300 lb. man like myself. So satisfied, I bought a second pair for my other shoes. These are better than the ones from my podiatrist. Thank You for the relief I've gotten from your product at a great price.

      — John S, US
    • Weight Tested

      One of the first arch supports that didn't collapse when I put my full weight on them (285lb.)

      — Ed, US
    • Best insoles ever!!

      I love that the arch support stays sturdy. It doesn't collapse like other insoles. I have severely flat feet, and (with the help of OrthoFlexx) I was able to wear all of my sneakers with total comfort and no pain. I would definitely purchase more!!!

      — Danielle K, US
    • The pain has gone away

      My feet have been hurting for awhile,I am on them seven days a week for 12 to 14 hours a day. l put them in my boots and the pain has gone away. I’m a believer Thanks pat

      — Patrick V, US
    • They are great insoles

      They are great insoles. Very comfortable. My only complaint would be that they are quite thick so they take up a lot of room in the shoe.

      — Abigail W, AU
    • These are the best inserts I have found

      These are the best inserts I have found. Years ago I had to get them from a podiatrist and they cost me $450. These are just as good for a lot less money. I am on my feet all day and this is made a huge difference.

      — Lori K, US
    • Great Insole

      These insoles are a game changer for me. I am in construction and my feet no longer hurt after a long day of work. The arch support is robust and seems like it will hold up a long time.

      — Dan, US
    • I like the greater arch support

      I like the greater arch support. Only gave it 4* because I would have liked a higher arch support.

      — Frank, US
    • Very impressed!

      I am quite pleased (and a little surprised) that these insoles don't collapse by the end of the day. I have had plantar fasciitis for a few years and nothing has helped. I have started to see a noticeable improvement after only a short time! I would definitely recommend.

      — Nancy O, CA
    • Absolute game changer

      Bought these insoles due to falling and hurting my ankle, needed to keep it from rolling inward. I’m on my feet all day and was skeptical that these would make my feet less sore in general. I have to say been three weeks using them and I absolutely love them. My feet are less sore my knees actually feel a little better along with my lower back…absolute game changer.

      — Robert D, US
    • I don't recommend for wide feet

      I don't recommend for wide feet. The side of my foot and my pinky toe hang off the edge. I can feel it and its annoying. Because of the bulk, my shoes are now too small. I have to buy a larger size shoe

      — Wrenn, US
    • My knee pain is gone!

      I walk 3 miles most mornings and began having knee pain, especially in my left knee. I read that as we age the arch in our feet begins to collapse which throws off our alignment up the leg all the way to our back. MRI showed only arthritis in my knees. I tried Orthoflex in my sneakers and my knee pain is gone. The support in the arch of my feet is like a welcoming massage. I wish I tried them sooner!

      — Ellen G, US
    • Highly recommend

      The only shoes ive been able to wear in the last 10 years that dont cause me foot pain are my custom made work boots. Ive tried sooo many insoles with tennis shoes and none worked for more than a few minutes. Three days wearing my new orthoflexx insoles with tennis shoes and i had no pain being on my feet. Highly recommend this product.

      — Rick, US

    Frequently Asked Questions

    Before you order

    Will they help with my condition?

    Max is built for flat feet, plantar fasciitis, high arches, bunions, and overpronation.

    It also helps with heel, knee, and back pain that comes with them.

    Not sure? Take the 60-second insole quiz.

    Are they too firm for me?

    Max is firmer than most arch support insoles, on purpose.

    A softer arch flattens under your weight and stops doing its job.

    Already tried arch support insoles and found them too high or too firm? Try our Light Arch Support Insoles instead.

    Will they fit my shoes?

    Yes. They work in most sneakers, work boots, walking shoes and casual shoes.

    Remove the flat insert your shoe came with and trim the toe if needed.

    Trimmed insoles are still covered by the guarantee.

    How do I choose the right size?

    Choose your usual shoe size.

    Between sizes? Go up one and trim the front.

    Still unsure? Email support@orthoflexx.com with your shoe brand and size.

    Do they work for wide feet?

    Max comes in a standard width, not a wide fit.

    Wide options are coming soon.

    If they feel too narrow after a few days, the 30-day money-back guarantee covers you.

    The first few weeks

    Is there a break-in period?

    Yes. The first day or two can feel high or a little sore.

    Start with 2 to 3 hours a day and build up.

    Most people feel clear relief within 1 to 3 weeks.

    What if they hurt after a few days?

    Mild soreness in the first few days is normal. Your feet are adjusting.

    And some feet simply don't adapt to our insoles. If the pain doesn't settle, email us. We'll suggest a better fit from our range or issue a refund. You have 30 days.

    Can I move them between different shoes?

    Yes. Many customers switch them between work boots, sneakers and walking shoes.

    A lot of people end up buying a set for each of their most-used pairs so they never have to swap.

    Shipping, guarantee and payment

    Where do you ship from?

    US orders ship from our US warehouse, so delivery is fast.

    International orders ship from the warehouse closest to you.

    How long does shipping take?

    Orders are dispatched within 24 business hours with full tracking.

    Most US, UK, CA and AU customers receive their package within 3 to 10 days.

    Shipping is free on every order.

    What if they don't help my pain?

    30-day money-back guarantee.

    Email support@orthoflexx.com with your order number, and we'll refund you.

    Can I pay with my HSA or FSA card?

    Yes. HSA and FSA cards are accepted at checkout.

    Care and durability

    How long do they last?

    The firm arch platform is built to stay lifted under full body weight. Many customers get a couple of years out of a pair.

    Lifespan varies with weight, shoes and hours on your feet. Replace them when the arch starts to flatten or the top cover wears through.

    How do I clean them?

    Wipe with a damp cloth and mild soap, then air dry away from direct heat.

    Don't soak or machine-wash them, as that can affect the supportive structure.
