"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."
