If it wasn't for the zipper issue I would be giving these shoes four stars.  They fit well, are comfortable to wear and walk in.

Two problems though:

1) The zipper for some reason will not stay up at times.  I've tried to figure out if it is something I am doing, but there does not appear to be a reason for the zipper to sometimes slide open. It doesn't happen all the time or even most of the time, just enough to be annoying.

2) If walking over an area with large gravel or rocks, the sole doesn't protect the bottom of the foot as well as I would like.
