"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."

New generation is even better

I've been wearing Protalus insoles for nearly ten years. I always put them in my running shoes, and shoes where the insoles can come out relatively easily. The new generation M-100 is definitely superior to the older generation, where I felt some ridges on the bottom of my feet and toes. Not so with the latest design. I highly recommend this new M-100.

Great addition to my running!

I recently used the Protalus inserts to compete/complete the hardest race in the world, the Marathon Des Sables in the Sahara Desert. I was a bit nervous to see how the foam would react to the desert heat but I was pleasantly surprised and held up well. I had zero PF issues however it did rub one of my arches raw but that may have been due to the combination of the heat and sand. Overall, they performed very well and I was thankful for zero PF issues. I used them with my Hoka Challengers.

Great foot support!

I took a risk years ago ordering these inserts online. So glad I did. They have been awesome for my feet.
