Those that believe in the stripped down aesthetic of running shoes may misconstrue the decision to winterize a trainer complete with an attached gaiter as proof of complete disregard to the core principal of running shoes. Me, I'm thrilled that shoes have evolved beyond the thinking of one shoe for all activities. Shoes like this, with a Vibram Artic Grip outsole with Ice Trek technology and aforementioned gator, don't have specificities to what they can't do just things they're for. Which for the RAZOR includes responsive energy return (EVERRUN heel insert) and protection against the elements (Runshield upper.) Things they're against? Uncomfortable feet.
Midsole
EVERUN is a responsive cushioning compound that helps to distribute forces over a large area.
Upper
ISOFIT is a stretchable mesh that adapts to the foot's size, shape, and movement, creating an ultra-soft, sock-like feel.
Flex Film Overlays are made of a thin film that is welded to the upper for a snug, secure fit.
Runshield water-resistant upper keeps your feet dry throughout your run.
Fleece-lined neoprene is placed against the foot for added warmth and dryness in icy conditions.
Speed Lacing System provides easy shoe entry and exit and a secure fit.
Outsole
Vibram Arctic Grip in high-contact areas for increased grip on icy terrain.
IceTrek is designed with an aggressive pattern for flexibility and traction in cold weather conditions.
