They are very comfortable at this point and the strap over my foot feels snug, soft and fitted to the point that they are not given a thought about as i trek threw my day. But all in all this is a good product. My aero bars and how I have the bike set up kinda got in the way. This would be a great rack except that it was missing 2 wing nuts. Over 60 and can wear to work. time to test. BASURA. I love the cushion in these crocs. Holds it steady in place with no slipping. In my Box I think they only included 2 sizes of Medium Eartips by mistake, and they Forgot to include LARGE Size Eartips inside of the Box.
