"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."

Best out there

This is my second pair. I had my first for 7 years. And these are exactly the same except better because they are new. Great arch support. Just take out the foam inserts in a tennis shoe and these arches fit perfectly inside. Lifesaver!!!

Husband really likes them!

Very comparable to prescription orthotics through his podiatrist.

I was skeptical. These WORK

I waited two months to make this review, just in case. I've put around 50 miles into them, and so far everything is good. I had tendinitis in both feet for going on 15 years, was too stubborn to buy something to address it, having been perfectly fine for tens of thousands of miles. Finally at 50 years young I got the wallet out. I'll never run marathons again, but not because of these insoles. I just wanted to be able to run 20 or so miles a week, and I am well on my way.
