Mizuno Wave Horizon 9

Mizuno Wave Horizon 9 review: what runners say

Fit

Sizing improved from version 8 onward: sources indicate the shoe runs true to size. Available in widths, but the 2E version of the previous generation ran narrow through the midfoot.

Feel

Dense, structured cushioning: the heel is soft but the sidewalls are firm, providing stability without collapse. The feel is not marshmallowy — it leans toward the firm side, with some responsiveness from the top foam layer.

Durability

Mizuno is cited by multiple sources as a benchmark brand for durability. The shoe holds up without breakdown through a perceived 500 miles; the X10 outsole is described as highly abrasion-resistant.

Best for

Maximum-stability shoe for runners who overpronate or supinate severely, carry higher body weight, or deal with conditions such as plantar fasciitis and Achilles tendinitis. Also suited to everyday all-day wear and on-the-job use.

Weak points

High weight (over 11 oz, up to 13 oz in some sizes) compared to competitors in the same category. The 2E version of earlier generations ran too narrow through the midfoot; version 9 appears to have partially corrected the sizing.
