With today's athlete in mind, Vibram FiveFingers has raised the intensity with the Vibram FiveFingers KomodoSport collection. This aggressive cross training design inherits what we love about the KSO with functional improvements that appeal to the most active fitness enthusiast. For the first time ever, Vibram introduces a stitch-free, seamless 3mm footbed to reduce friction. Heel and instep hook-and-loop closures help secure the stretch nylon upper to the contours of your foot-just like a second skin. The KomodoSport wouldn't be complete without a 4mm Vibram TC-1 performance rubber outsole which provides the grip and protection you need for a variety of cross training activities both indoors and outside. Machine Wash, Air Dry.
