Unfortunately for me, the straps that go over the toes was too loose, but I wanted to comment on the brilliance of the buckle.  Why has nobody done this before?  Instead of awkwardness of buckling and unbuckling, you adjust the width of the buckle, then it just slides into place.  I want all my buckles to work like this. (Shoe manufacturers, please stop putting Velcro on everything!!! You're ruining my clothes.) Oh, also to the comfort...My daughter wore them all day and night and LOVES them.
