When I was in high school I had a pair of these that I wore before and after soccer games. Since then I haven't had a pair. Recently, when I had my first child, I discovered that my feet and my lower back were really achy after days of walking around our apartment in socks or barefeet. I bought a pair of these to give me some arch support and stimulate circulation. They did the trick! Seriously, I no longer have that achy back! They are comfortable and cheap and last a long time. If your slippers are warm, but don't offer any arch support, try a pair of these!
