I bought a pair a couple of years ago based on SB comments when my Bare boots wore out. They seem much more durable. I needed 2 sizes up from my normal shoe size and to go wide (I wear liner socks, wool socks, and booties on my feet inside my drysuit) and had to pull out the insoles to get them to work, but they've been great. No concerns, easier to get on/off than the Bares were, and seem like they should last a long, long time. My old Bares were about the same labeled size as my regular shoes, so if ordering by mail (as I did), getting the right size may require a return for a different size; I had to do that.
