K-Swiss Tubes Sport Trail Starfish/Black/Charcoal Men

Introducing the Tubes Sport Trail, a new upper inspired by our patented Tubes system. This technology provides unrivaled comfort and cushioning through individually tuned tubular structures that contract and rebound as you walk. The design also offers incredible flexibility, making every step smooth and efficient. A smaller, stiffer tube in the medial heel area provides additional medial support to reduce pronation. The Tubes Sport Trail also features an updated rubber outsole with a more aggressive tread design and rear outriggers to disperse any fluid you might run into. The design is completed with new TPU eyelets and heel pull.
