Z1 Diamond Stealth
I have been a Pro River guide on the Rio Grande for over twenty years. I've tried every sandal imaginable. When I started boating, wool socks and canvas tennies were the hot ticket. By far, the best sandals around are Chacos. No velcro! On the river, the velcro gets clogged with sand and is rendered useless. I don't understand the problem the other river guide had, I guess getting a lemon is possible anywhere. if you're going to use them on the river, get the diamond stealth sole. Off the river, get the Unaweep. The diamond stealth wears down fast on concrete, etc. The strap system on the Z1 is the best out there. Having swam various rapids with them, they have never come off my feet. I can't say that about most other sandals. In fact, some other sandals didn't come off my feet. Only half the sandal became detached, leaving the sandal flopping around your ankle while you're swimming for your life. The Z1 design also lets you use wetsocks in the spring. Much better than booties! And when you get off the water, switch out the wetsocks with fleece socks. Enough blabbering, Chaco Z1's rule!
