The velcro used is wide enough for a secure installation and makes installation and removal simple. One thing that I?d say Keens could work on is making the Velcro strap not so long, but that is such a minor detail and ultimately doesn?t bother us or impair the shoes ability to fulfill its purpose. I love that the hook is able to be moved around depending on what you?re holding. It will not hold any charge. Giant head, big ears, and these Vankyos dont hurt my head at ALL. It would fit lengthwise but would definitely be too wide. I was a staffer at a childrens summer camp from end of May to beginning of August. Very lightweight but a gorgeous and bright silver. Appear well made but the toe box is too small and the foot opening is too large. He is very pleased with the fit and feel.
