Fit is good. The arch is a little flat initially. However, after about 20 miles it starts conforming to your foot. I use these sandals for everything: work, basketball, handball, biking, soccer, hiking, and backpacking. When using for sports be sure to cinch tight for good lateral support and grip. In fact these sandals offer better ankle protection than most shoes. I buy about 3/8" long than needed to protect from bumping my toes. At rest, just ease up on the straps.

A feature of these sandals that you can't get in shoes is fitting the arch. Just center your arch on the sandal with all straps opened up. Then close the back strap. That strap shouldn't have to be adjusted ever again.

Also when backpacking and crossing streams, just walk through! They dry out fast. This is the all purpose comfortable backpacking foot wear. At night just loosen the straps for camp slipper feel.

The grip is about 10x better than vibram; especially on wet sloping granite surfaces. Spider rubber is amazing. They dry out very fast. I love open toe sandals because closed-toe sandals collects and keeps muck against your toes.  When doing sports, I recommend wearing with socks and cinching tight to prevent blisters. Socks keep the sweat wicked out from the bottom of your feet and eliminates shoe smell and athlete's foot.

The Terra Fi 2's were MUCH MUCH better at keeping out rocks. Now I have to stop about once/hour and use my finger to flick out a rock (it doesn't take much time though). But with the Tera Fi2's, I could go for 8 hours w/o flicking out a rock. Therefore I think Teva went backward in their design; and that's worth a point drop to me. Tera Fi2's are a 5 star.
