I wish I had the camera ready the first time my 6yo daughter tried climbing in these shoes. It was a revelation:"Mom, they STICK to the rock!!!!!!"
The shoes seem very comfortable. My daughter wears them for hours at a time. In fact, we have to talk her into taking them off when it is time to hike back to the car.
The fit is fairly narrow, the velcro is easy for little kids, no adult help required.
The red color really stains the feet, that's the only negative thing about them, though my daughter thinks it is a cool feature.
