I really wanted to like these and do but the grey portion (trim?) seems to be like a rubber almost and it is rubbing on my skin and causing scar and tissue to rip off my foot :/  They look awesome though and feel great when not walking just the walking causes the issue. I tried to wear them a little less or with socks now.  **Updated 12/2015** So after having these and using them a few times a day for 6 months they are now trash. They have torn apart on the sides and thus can't hold a foot. Both have done it now. It started with just one and shortly later the other started.  Cheap made is all I can say. I've never &#34;washed&#34; them or gotten them wet etc. so no excuse. I've got much older other brands that last better.  Too bad I can't have my money back :/
