Introducing the Tubes Comfort 300, 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, leather, and TPU hot melt upper provides structure and breathability to this style while still being very wearable.
