I bought these sandals specifically for hiking in the backcountry of the Colorado Rockies. For a number of years I was using the Teva Obern sandal which was a great sandal for all types of terrain, talus, scree, boulders, tundra and trails. So when Teva stopped making the Obern I had to find a new sandal, bummer. It was between the Toachi 2 and the Terra FI 4, I ended up choosing the Toachi for two reasons, the water draining feature which is really awesome since I have to forge through creeks and lakes often when off trail and the plastic clip which is great for everyday use. When I got this sandal out in the backcountry I found out this sandal is totally designed for boat use. It has absolutely no use in the backcountry since there is very little tread and the foot bed is very flimsy. I've taken this sandal out in the backcountry four times on 10-15 mile hikes often with no trail and every time I have taken a fall because of the sandals and I almost never fall. The last fall I took I did some damage to my toes and I will be out for recovery for at least six weeks before I can aggressively start hiking again. For everyday use this sandal is very comfortable but that's not what I need. I found a pair of Obern's on Ebay but they are a half size to big so if they do not work I'll give the FI 4 a try and see how they compare to the Obern which was a bomb proof sandal.
