Propet Men's Ultra Walking Sneakers - Comfortable Black Athletic Shoes for Walking, Hiking & Daily Wear

This is my 4th pair from propet, it has been a game changer for walking comfort. Unfortunately, this pair for what reason the inserts are crumbling on the bottom. They gave me the option to return but I decided to keep them and use an insert from my oldest pair of Propet sneakers. I wish there was a way to get replacement inserts. In any case great comfortable sneakers, but the insert is a disappointment.
