K-Swiss Men's Tubes 200 Trainers, Surf The Web Ice Flow White, 7 UK

Introducing the Tubes 200, a trainer that features 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 breathability to make this shoe one of the most comfortable trainers you will ever experience.
