Almost the perfect shoe for anything if you get the right size. I sent back 1st pair, no reviews on new model so found out hard way sizing is a bit off. Definitely size down a half size! They are long! Also note that if you're feet are at all wide, go for wide version. I have normal width(4 1/4 at widest point) feet and its snug on me. My only real complaint about these shoes is they could use about 10% more arch. My arch is medium height. They're so comfortable I didn't even notice until the end of a long work day. Could also just be due to my current (194) weight. Color/design is fantastic, though I would like to see more color options like previous models had. Hopefully they just haven't launched full line-up yet, since I purchased in first month of availability. Also, these are seriously better than my expensive Kayano lite 2's.
