The oversized Velcro closure creates loads of adjustment at the top of the shoe to help as the growing kid's foot widens. The rear Velcro heel strap allows for plenty of adjustment as the child's foot grows, creating a tight fit for the life of the shoe. This was the first shoe to have the Velcro heel strap and it's popularity has been unmatched as a result. There must be some mad little climbers out there who have had every size of this shoe as they have grown up.
