K2 Inline Girls Charm X Boa fall out much too small. Size M is not 32-37, but rather 30-35, if not less. The Boa closure is good and easy to use, if you know how it works. Instructions, is absent. Children can dress well without help alone the skates. Must be tightened so that the skates are properly the closure, which will cost some force. Therefore, recheck better again whether the children seal the well properly. Two of the wheels blocked at delivery. What I think is a pretty catastrophe. Here you pay clearly the name K2. The quality is poor. Same or even better quality you get for half the price.
