I got a pair of Nano 2.0s to do crossfit in and I love them. I wanted something similar to walk around in that wasn't as crazy looking and that's a little cheaper so I gave these a shot. I think they're incredibly comfortable. If you're familiar with the Nano 2.0, these are about the same cut and fit. They have a slightly softer sole (foot bed?) than the Nanos. I haven't tried crossfit in them, but they seem like they'd be fine for that too. They don't seem nearly as durable as the Nanos, though. Overall, for just walking around I love these things.
