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.
