"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."

Hi Scott,

Thank you for taking the time to share your experience and so sorry to hear that you received the wrong size. We did notice that you were able to get that exchange set up so you should be all set, but if you have any questions at all, just let us know. :)

Best Regards,

Pain free

I have been suffering with plantar fasciitis for 7 months. Several visits to podiatrist, several brands of

Insoles with no relieve. The M100 allow me

To play pickleball without pain. Usually I am 11.5 size in sneakers, but sneakers were somewhat tight. Going up 1/2 size have my sneakers feel totally comfortable.

Not sure

I’m still trying them out. I have a feeling that I need an orthotic thinner than this. Not sure about the heel fit.

I might have to return them.

Protalus

Hi Jeri,

Thanks for taking the time to share your experience! We do have a slightly thinner version of the M100 that you have - it is the T100 and you can set up an exchange if desired here: https://protalus.com/pages/returns

You have a 90-day guarantee so you have plenty of time to keep trying the M100 and still exchange for the T100, to give them both a good try. :) Let us know if you have any questions!

Best Regards,
Nick

Great Product

I used to live in Fl. and wore sponge flip flops 24/7. I paid for it eventually, I developed Plantar Faciatis. Well, I no longer wear sponge flip flops and I wear Prolaus inserts in all my shoes. Very comfy and have had no problems since. Been wearing Protaulus for over 5 years now. They're the real deal.
