Great option for replacing the insoles in minimalist shoes. I bought a few of these a while back directly from NorthSole and loved them. When I was shopping for grip socks here on Bearfoot, I saw they carried these so I grabbed a couple more. Easy to trim to size, very comfortable without degrading that barefoot shoe feel. Definitely recommend.

Just enough cushioning to protect from rocks and stuff. Easy enough to size and trim for my shoes.
