There is a shoe version of these and I would recommend those but these are horrible and I regret purchasing them! These Crocs are so pretty and comfortable, I love that the company is offering more than solid colors to chose from. In fact the Hollywood-isms scattered throughout this story are pretty amusing. With the first one I thought it was just the holiday season slowing it down. Because silicone is grippy and stretchy, just have to use some finger power to get it there. Vendor shipped quickly. Así que al final terminé decidiendo comprarlos de nuevo. It barely secures my wifes bike which is 26 inch tires by 2. When I got them, I thought uh-oh. On a side note, My dog loves them and tries to steal from me!
