These things are so light I feel like I should put a lead weight in each one to keep it from floating away. And they are VERY comfortable. I have foot problems and have a very hard time finding shoes that don't hurt.

On the down side, the materials and assembly are about as cheap in appearance as I can imagine. Wearing them twice a week, I doubt they will last a year, while I am used to my shoes (not nearly as comfortable as these) costing about the same lasting around ten or more years.
