John N. wrote a review of Teva Zilch Sandal - Men's on September 8, 2011
After losing my '98 Reefs while crossing the Merced River this summer, I decided I needed a new pair of camp shoes / water shoes to take backpacking. I wanted them to be light and low profile, and when I saw these reviewed in a magazine I had to check them out. I recently received them (on sale through another site) and after a few wears I can say that they fit the bill perfectly. I generally wear a size 10.5 - 11 in sneakers, and I ordered a size 10.5 in these. They fit my feet almost perfectly, so I guess my experience just adds to the sizing confusion below. I think the issue with sizing is that these are designed to really fit your feet closely and ergonomically, which unfortunately can't take into account just how different everyone's feet are. Perhaps I got lucky, but from my experience these run true to size.
I can also attest that the toe strap DOES stretch to accommodate a larger toe in time, and it is really no problem. The only issue I have is that the fit tends to want to push my heel off the back of the shoe and because the rear strap is not adjustable, I have to deal with a tiny bit of my heel spilling off the back of the sole. I counter this by loosening the front strap. Again, I think this is due to trying to make a "generic" ergonomic shoe. Despite this caveat, I really, really love these things and they are light enough to clip to my pack without stressing too much about added weight.
These are my first "barefoot" shoe, and I really like the feeling. I have not used them yet in stream crossings, but I imagine they would perform like any other Teva-type sandal.
-"Barefoot" style low profile sole
-Comfortable on feet
-Ergonomic streamlined fit
-The streamlined fit might *potentially* cause problems with individual feet
-Rear strap not adjustable
Overall I would definitely buy these again...
