Yonex upgrades its top shoe by keeping all its key technologies and upgrading the stability through the heel area. A new external TPU heel cradle wraps around the back to offer more lateral stability, and with mesh vents in the heel, your feet will stay cool as well. A built-up medial side offers excellent durability and a flash of color. The 308 continues to feature ToughBrid, which provides better bounce back of material with more elasticity in a lightweight substance. This keeps the shoe light while continuing to perform in comfort. This version continues to feature the Power Cushion technology in the midsole and insole for that responsive, comfortable ride. Another continuing technology, the Super Ergoshape again enhances comfort. Yonex says Super Ergoshape provides maximum forefoot and toe comfort.
