Combined with Mizuno Wave technology and XPOP the new Wave Horizon 5 provides an even softer landing whilst supporting the movement of the foot from toe-off to landing. while the XPOP insert is longer on the lateral than the medial side to deliver stability whilst delivering a comfortable floating feel. The midfoot support panels, on both the medial & lateral sides, create a structural hold in a key area to deliver secure hold on the runner's foot, providing you with additional support.
