"The new M-100 insoles have been a game-changer for my foot comfort. From the moment I started using them, the cushioned support and perfect arch alignment provided instant relief. They fit easily into my shoes and stay in place without slipping. Most importantly, they've significantly reduced my foot pain, especially after long days on my feet. I no longer experience the soreness I used to, making walking and standing much more enjoyable. If you're looking for comfort and pain relief, these insoles are a must-try!"

"I have been a Protalus customer since 2020 and have been consistently pleased with the performance and durability of these inserts over several iterations. From the start, I found the Protalus inserts comparable to my prior custom orthotics, and a MUCH better value. The new M-100s feel terrific, with perhaps more stabilization for my heel, and a slim profile that allows ample room in my shoe."

"Put them in a new pair of shoes, they replaced the original shoe insert. The M-100 was comfortable, no foot pain."

Super sturdy & supportive

I don't care if you've tried every other orthotic available - if you have foot, ankle, knee and even hip or back pain, you owe it to yourself to at least give Protalus a fair trial. I've used everything from off-brand chain store inserts to expensive so-called 'specialty' orthotics to prescription inserts and custom made ones. Protalus beats all of them. I bought a pair way back when they were first introduced, and I loved them. I'd always meant to get on a subscription plan, but somehow never did. Fast forward to December 2025 and I decided to treat myself. The form and materials have changed somewhat, but the fit and support and durability Protalus has become known for is still obvious - if anything, it has improved. I highly recommend either or both the M-100 and the T-100 (depending on what shoes you're putting them in). Well worth the investment!

MY M-100 INSOLES

Best ever shoe inserts. Planter Facittus is noticably better as soon as I placed them in my shoes and started walking. I noticed feeling like my body allignment seemed to be better. I highly reccomend these to any one that has issues with their feet. My neuropathy also has improved.
