Familiarity: I've put it through the wringer
Fit: True to size
I always had a terrible pain in my heels because I have a high arch and flat flip flops or sandals would just make it worse. The Z2s have great arch support so I can walk for longer periods of time (i've been in short hikes with them) and there is no more pain!
Downside is the length of the remaining strap. I normally just roll it around the ankle strap, but it comes off.
