I've worn these sandals fairly regularly for about 5 weeks.  They are comfortable enough, I wish the straps were a little closer to the toes in front.

The biggest issue is the placement of hook/loop closure (velcro) The top strap is fine, but the strap at the heel was placed to look good while still in the box.  After you put the shoe on, the loop section only overlaps the hook section by about 50%. The remaining hook area at the back of the heel has a tendency to catch hold of my pant leg.  Another issue with the hook/loop material is that it is getting stringy: it is fraying at the hem because it is a raw, unhemmed cut, and not finished at the edges.

Otherwise the stitching and the sole material are just fine.  My old Teva look-alikes were purchased for $14 and lasted constant wear for about 5 years... things aren't like they used to be in so many ways!
