I somehow failed to notice this until after Id put them on! Luckily, the back of the shoe is adjustable, so it fits properly around the ankle which is a perfect setup for me, since my ankles are narrow. It was just one block for the same price. :)UPDATE: They are holding up fantastic! Ive been meaning to write a review for some time now, but a recent encounter with an inferior, barely used cable has awoken me to write this review. We all get what we pay for. I think its better than the handle bar mounts as far as visibility, longevity and safety. It has grooves that run the length and others running across. Ive ridden places that will rattle the teeth out of your skull (ie: the Whole Enchilada in Moab, Utah) and my phone never moves a bit. That being said, its great!
