The Tubes Comfort 200 features K-Swiss's patented Tubes system, offering exceptional comfort and cushioning with individually tuned tube structures that collapse and rebound with each step. The shoe's design enhances flexibility and smooth stride efficiency, while smaller, rigid tubes in the heel area provide extra medial support to reduce pronation. A lightweight mesh upper ensures breathability and coolness, making the Tubes Comfort 200 one of the most comfortable trainers available. It includes a textile upper, textile collar lining, rubber outsole, molded EVA midsole, and Ortholite sock liner.
