I am very happy with the ankle id. I also wear it over my sock and don't notice I have it on. In the cold weather, I wear it over my socks, tights, and neoprene boots. I didn't have to size up, there's plenty of room for expansion.

I also like that the reflective strip on the ankle band--in conjunction with the movement of the pedal stroke-- works really well to let those driving vehicles see me when I'm riding after dark, in the rain, or on grey winter days.
