Others have commented that the straps on this shoe are slightly too long, but for me, they are long enough that the shoe can't fasten at all.  The piece of velcro at the side of the heel on both sides is about 2 inches long, so normally, if you had to pull them a bit tighter, you might have an inch of overlap or so.  For me, if I tighten the straps so that the shoe fits my feet, the two sides of the velcro miss each other by an inch or more (meaning that each strap is about 3 inches too long).  I considered cutting the straps and reattaching my own velcro, but I think it's a lot simpler just to return them.

If you have narrow or small feet in general, look out!  It doesn't look like the shoe is designed with nearly enough flexibility in the straps.
