Mount pedal grip to the wall stud first, then use a plank to level and mark spots for the tire brackets. Exactly as described and a brilliant replica replacement for a broken headband. Easy to install! We may order another pair of these for our daughter. I was seriously disappointed with this. The uppers, in black in my case, do get scratched very, very easily but thankfully, a bit of rubbing with the pad of a finger seems to fix things. They had them in my size, which is 7 but I took a chance on the wide, which these sandals were. The item is terrific for the reasonable, economical price! I had a dongle on my keys, lost it twice. Great for aging skin that still has a few years of use to go.
