Saucony Xodus Ultra 4

Saucony Xodus Ultra 4 review: what runners say

Fit

Generous fit through the midfoot, with two offset eyelets that improve lockdown over the instep. Moderately tapered toe box: runners with wide feet flag some reservations.

Feel

Dual-density midsole with a PWRRUN PB core and PWRRUN EVA frame: soft, reactive cushioning in torsion, stable platform. The pronounced rocker aids transition across varied terrain.

Durability

Engineered mesh upper with TPU overlays; 4 mm Vibram MegaGrip outsole with rubber over 2 mm thick. The switch from the v3's Power Track to Vibram resolves the premature wear issues reported on the previous version.

Best for

Built for ultras and long distances on moderately technical trails, dirt, and fire roads. Works as a trail daily trainer as well. High weight (306–338 g) rules it out for fast racing; 4 mm lugs are borderline for deep mud.

Weak points

Weight is the most recurring criticism: more than a gram above the main competitors in the category. Some runners report the heel padding breaking down faster than expected over time.
