Yonex updates their most stable tennis shoe with the Men`s Power Cushion Eclipsion 4. Yonex created a roomier toe box and forefoot to improve the fit of the shoe over the previous generation. To add agility to an impressively stable design the brand incorporated a new 3D POWER GRAPHITE DRIVE. The technology includes a 3D graphite plate in the midfoot for quicker reactions and faster acceleration. To improve the overall comfort, a new Feather Bounce FOAM was inserted into the midsole. Power Cushion+ returns in the forefoot and heel to improve energy return and cushioning, and the heel is further stabilized by a TPU HEEL STABILIZER. The shoe`s one piece outsole design is built to hold up during the toughest matches on hard court surfaces.
