These shoes stand up to abuse. I've been wearing the heck out of them since I got them. I bought the ones on sale so the color and style are not really to my tastes but I quickly got over it after wearing these.
What I like: they are extremely breathable, they have that slim/barefoot technology that I love, they are easy on/easy off.
I would compare these to a pair of Sketchers I got in gray/black that had the same slim profile. The Merrells are more comfy and more "breathable". I prefer these for actually walking in. They're good for travel - forget Hollywood, you need to be wearing good shoes in case of emergency! I would be interested in trying other styles in their line. I just didn't want to spend alot of money until I had tried them out.
