Is the thickness of the sole the as the filters or thicker? i like the filters but i dont want to make too much of a change. Also does the black outsole last as long as the gum outsole?
You can't can't feel that it is thicker, just nicer. The change won't bother you except for the fact that you won't wear another pair of filters again. The Poron is great and you will love it.
