The shoes are very comfortable and work great, however after 2 training sessions the velcro came loose from the strap at the top leaving the strap just dangling and not holding the shoe firmly to my son's foot. I expect better quality from Nike especially for the price I paid just a disappointment. I can't even return the shoes and re-order the same shoes in the same size on ebay without paying a new price that's $100 more. Annoying!
