Mizuno’s best loved running shoe just got better in the new Wave Rider 20. The latest midsole incorporates a new U4ic compound which is 33% more responsive than previous models. Now with a newly redesigned Neutral Wave plate for softer cushioning, this shoe offers unbelievable responsiveness with every step. An articulated U4icX heel wedge allows the back of the shoe to pack in more cushion and a softer feel. To keep your foot in place, Mizuno’s Dynamotion Fit features a Triple Zone engineered mesh to increase breathability and movement. For additional comfort, a softer collar prevents irritation while holding your heel in place.
