I am annoying my new z-kickz. I wear size 7.5-8M depending on the shoe manufacturer. The size 8 is fine and the shoes are light. I've been doing Zumba at home with my Wii and frankly our wooden floors could use a refinishing/ replacement. These shoes helped my slides and pivots. I recommend them. They don't feel as cushiony as a running shoe but they also aren't hard on the soles.
