When I received the box and opened it I immediately panicked. While I knew these shoes were supposed to be on the lighter side I couldn't believe how light they were, and wasn't sure there would be enough cushion and support for my weekly mileage - which can top off at 50 miles. However, when I ran for the first time in them tonight they were kick-butt awesome! Ran a fast 7 and felt great! I agree with other people that the back is high and the fit is narrow, but these are two features I like in a long-distance running shoe. My feet did not slide side-to-side like in my Ride 5's and I felt fully supported around the ankle. Lastly, if a shoe can be sexy (which I think they can) these are stinkin' hot!!!!!!!!!!!!! They are the best looking running shoes I've had in half a decade and they perform to boot - can't ask for much more, unless they could come with Channing Tatum in the box. If you're a small runner who doesn't pronate, looking for a fast shoe with looks, don't hesitate to buy - the Kinvara delivers.
