Most people know that Chaco designs great footwear, though, the Z/2 Unaweeps are above and beyond "great" footwear. I recently got these in a swap for a pair of older Unaweep pros which had the sole wear through. I mean completely through, one day I kicked them off and Wow! the strap was visible and the sole was partially gone. Luckily, I was in SLC visiting my girlfriend and dropped in the Warehouse to get an exchange. The next day, we headed South to the Grand Step, outside of Boulder, UT for an extended camping, hiking and backpacking adventure. These performed amazingly on the windstone and sandstone in the region. The footbed is comfortable and the sole has an updated, more technical and durable tread pattern. Through water, wind, Sun, snow and sand these carried me everywhere. I wear them everyday, it feels like, and could not be more pleased. Highly recommend! Just be wary, sand will get in the sandal at the straps and make it near impossible to adjust easily, as well as chew apart the straps due to the abrasiveness of sand. Just turn them over, pull the straps side to side and empty out the sand. Then pull the straps to all different configurations so the remaining sand falls out. This and some Nikwak Sandal Wash should keep your Chacos going strong for miles.
