In addition to several smaller updates, the Mizuno Wave Rider 20 received a new wave plate and a U4icX foam heel wedge that give the shoe a softer landing and added responsiveness. Building off of those updates, the Mizuno Wave Rider 21 retains the midsole and outsole design of the Wave Rider 20 while incorporating a reformatted upper and a new, premium sockliner that should improve the fit and comfort.
To maintain the lightweight and responsive ride of its predecessor, the Wave Rider 21 includes U4ic midsole foam with a U4icX heel wedge to offer responsive cushioning and a soft landing under the heel. It also incorporates an identical Cloudwave plate for additional underfoot spring.
The primary differences between the Wave Rider 20 and the Wave Rider 21 are the updated upper design and the new sockliner. For the Waver Rider 21, designers use new Dual Zone mesh in the forefoot that should improve breathability and flexibility without sacrificing the hold. The heel collar has also been softened to increase comfort. In order to further improve the underfoot fit and feel, designers added a new, premium, anatomical sockliner.
Because of the new design, the men’s Wave Rider 21 weighs 0.8 ounces less than the previous version while the women’s weighs 0.3 ounces less.
