Actually M-100 Lite

I am a longtime user of Protalus inserts. I loved the M-100 because I’m old and need the extra cushioning it provided. A year ago I saw that the M-100 was being discontinued, so I bought the M-100 Elite and it was ok in my last shoes. I recently bought a new pair of Hokas that don’t have much cushioning built in, so I decided to get some new inserts.

I was surprised to see the M-100 back and decided to order it. When they arrived I saw that the label said M-100 lite. I decided to keep them, but after a couple of weeks it is obvious that they don’t have the cushion

Ing that the old model had.

They still have plenty of arch support for an old pronater but not enough cushioning.

So, my suggestion to anyone buying off the website is to be very careful.

Hi Brett,

Thanks for taking the time to share your experience! The new M100, sometimes referred to as the M100 Lite, uses new materials that we developed to resist compression, resulting in a longer lifespan while still getting support, correction and cushion. The M100 Elite does have a thicker profile with more cushion and we would be happy to exchange if you like! :) We will pass on your feedback to our design team as well.

Best Regards,
Nick

Very uncomfortable

Been wearing these for over a week now, and its very uncomfortable on my feet. I stand/walk for my job for 6-8 hours a day. These insoles are way too hard and badly shaped. I will be refunding them. Do not recommend.

Super Support!

I first purchased the Protalus shoe inserts from a special on one of the morning shows (can't remember which show). I have to say these are the best inserts I have ever purchased. I have flat feet and all kinds off foot issues and have worn expensive orthotics. As soon as I inserted these in my sneakers and wore them, I could feel a major difference. These are so good that I had to purchase another for my other sneakers. I will be repurchasing these in the future. I say give them a try, highly recommended.

Support at last

I’ve needed arch supports for a long time and Protalus provides a reasonably priced alternative to prescription made supports. My new shoes now have the Protalus support and I have my walking shoes ready!
