K-Swiss Men's Tubes Sport Training Shoe

Introducing the Tubes Sport, a new from the ground up update our patented Tubes system. The technology provides unmatched comfort and cushioning through individually tuned tube structures that collapse and rebound as you walk. The design also provides incredible flexibility making every stride smooth and efficient. Smaller, more rigid tubes on the inside area of the heel provide extra medial support to reduce pronation. A lightweight mesh upper provides additional coolness and airflow, while the TPU stripes and mudguard provide stability.
