I am really happy with these and I very much recommend them. I use custom orthotics and I have one particular pair of casual sneakers that I always wear around the house. I was wearing them barefoot. I realized that I should protect the custom orthotics from all day barefoot walking around the house every day. I looked at many of the available inserts here on eBay and chose these, and happily I selected these. The gel underside is really well made and cushiony with a thicker area at the arch. The top side is a sort of felt-like material perfect as a shoe bottom and very comfortable barefoot. I've been wearing them now for about a month and could not be more satisfied. Nobody paid me or anything to give this review.
