Cant wait to put it to use! The way its attached to the shoe is a little weak and the velcro didnt align perfectly to secure so I could feel it a bit but then again I am pretty particular about these things. They do not come out. I ordered it for my daughters upcoming prom. The dongly bit is not only annoying but is prone to getting damaged. These hooks are affordable but well-made and large---not skimpy at all. My 2yo can take them off on his own but definitely needs help getting them on. But the sizes are all over the place. My only real form of exercising is running and I think these are really great running shoes from the fit and support and the comfort. Since then there have been absolutely no issues with pairing or connectivity.
