SAUCONY Endorphin Pro 4

Description

The SAUCONY Endorphin Pro 4 is built for runners who want an aggressive, race-ready silhouette with a surprisingly comfortable, bouncy ride. With a redesigned midsole and updated upper engineering, it keeps a soft-yet-responsive feel while adding stable support—ideal for advanced runners and anyone who loves lively cushioning.

Up top, the premium PWRRUN HG foam is supercritically molded to improve energy efficiency and rebound. Underneath, the durable PWRRUN PB layer adds a springy, responsive underfoot feel—helping you stay smooth and comfortable at faster paces without feeling harsh.

For speed, Speedroll technology pairs with SAUCONY’s proven full-length carbon fiber plate. Its unique shape supports quicker turnover and a more efficient forward roll from start to finish, helping you transition cleanly through each stride.

Underfoot, an ultra-thin layer of XT-900 carbon rubber boosts traction and durability while keeping weight low. A breathable single-layer mesh upper with a flat-knit tongue delivers a comfortable, sock-like feel, and the 8 mm drop supports a natural, efficient stride for both training and racing.
