I am sitting on the couch working and using my Yoga Toes. I got a pair for Christmas and love the way they make my feet feel. If you haven't heard of Yoga Toes they are simply toe separators that are made of a very lightweight, flexible gel. And they're not cheap! Overstock.com has them for $44.99.
I will say that my feet feel more relaxed after using them and I haven't had any foot cramping of late. There are some great testimonials on Overstock from others who have ordered them. I was thinking of getting my mother a pair for her birthday which is coming up next week as she always has foot aches and pains. They do tell you to start out wearing them only 10 minutes a day and gradually build up to wearing them longer. They also claim to help with circulation.
