They didn?t cost a lot, so I wouldn?t cry if I lost them - I?d just buy another identical pair. The only thing I dont love about this is that the tension on it is a little tight that has some push back on the bike as you put it in there. I really like these. As an aside, if you are interested in a simple GPS app for using on your phone while riding, try GPS Odometer. I love chacos but these started fraying at the heel strap within a month. It served its purpose though and I am pleased with my purchase. The piece between the toes irritated me so I cut it off and you cant even tell . We purchased one of these racks and then another because the first one worked nicely for us. Starting a new bracelet buisness contact me if you are interested! Hes only in 4K, so wears them a few hours four days during the week while indoors.
