These are comfortable easy to skip on & off and have just enough arch support for light walking in the house. However, use your own screws as all three types of the screws that come with the hooks are cheap junk. I would like to further support this company despite the minor hiccup. Was offered a refund or a discount to keep them, but not the product as advertised. Make sure that you have a slender pair of tweezers to put the pin on one side back in(you have to remove one pin to snap the hinge in place). I ordered size 7 navy crocs tell me why I just received these in the mail. Does not seem like it would scratch the bicycle because the ends are rubber coated. They also seemed to run smaller. Son amplios y están más grandes de lo que parecen. Los conseguí a un buen precio y estoy satisfecho con el producto.
