According to most reviewers they ran small so I went with the size 10. Build quality overall is just barely average. smartmi link Although I love this product, and order it all the time, the material in the thong bands has been changed and this last pair is giving me dark black marks on my feet when I wear them! The threads on one of the wheels were a bit rough, and it didnt seat quite as well as the others. smartmi link I opted for this one over others as I have bought from the company before and their products are usually great quality and this is no exception. smartmi link Love that it’s a tough rubber like material, love that it has the light and button cut out which is why I’m keeping it. Nothing to worry about here. I was able to wear these for multiple hours at a time, only readjusting them a few times in that period. smartmi link Looks great on my electric commuter bike. I couldnt locate the womens version in my size so I subtracted 2 sizes for the mens.
