I also have the classic Chocos but I like Zvolv Sport the most. They fit the contours of my foot the best, with deep healing for healing and arch support. I use them for adventures in Hawaii. I'm a private Maui adventure guide, so the Zvolv are great for hiking in and out of streams, rock jumping, and waterfall jumping. I even wear them when I swim in waterfall pools. The straps are very strong, adjustable and the sole is flexible and durable. This is my second pair of ZVolvs because I lost my first pair after a year. So I already have a lot of experience with them.
