I've definitely jogged and hiked in my Keen H20 sandals. Excellent for this type of stuff. I'd never jog in bike sandles or shoes of any kind, though. I have to admit, I have a Keen problem -- when I see them, I must have them. I have fat feet, and they are excellent for me. I wear them at work and there is SO much support in them! (much more than you'll ever get with Crocs). And they seem to last forever.
