Details
This shoe features cutting edge Blade-Light technology, engineered to shave minutes off your time while training or racing. These shoes are very neutral so keep that in mind if you need posting for overpronation correction.
Anatomically placed K-EVA "blades" are aligned to the angle of impact and critical flex points for ultra-light, super cushioned, and amazingly flexible ride. The top layer of low density(52d)K-EVA in the GuideGlide format provides second stage impact protection and natural foot guidance. A micro layer of Superfoam sits underneath the K-EVA sockliner to provide a soft and resilient feel under the foot.Weight = 9.3oz
These shoes fit narrower across the midfoot, and have a slightly less roomy toe box than the original K-ONA line by K-Swiss. Also, note that most men are sizing up a half size from their typical running shoe for sizes up to 12. Sizes 12 and up typically do not need to size up a half size
