"I have a high arch or used to. I got this to test out and now after trying them for a while I'm really liking it a lot. My arch is slowly coming back and when putting into the sneakers it helped change the way I walk a bit. First two days were annoying and was about to give up and then BAM third day it was doing it's job perfectly. i would recommend not wearing white socks with it. It makes it look like you were walking on some nasty floors."
