How do I buckle these shoes?
Having trouble with the quick release buckle? ... then:
1st - the buckle is already on the strap, so simply find the right strap's hole (i.e. lenght you need to fasten the shoe) for your foot. And be aware that it may vary from left to right foot.
2nd - next pull the strap a bit (so the buckle goes a little past the closing position) and make the strap slide through the opening on the hook (the fixed part) and pull. If the strap feels loose adjust it; dance shoes are supposed to be tightly fastened. To open, pull the strap make it slide out of the hook and you're done.
