Expanding the Endorphin franchise with this high-tech powerhouse, Saucony have crafted the outstanding Endorphin Trainer. Built for runners who demand both speed and durability, the shoes bring race-day innovation to everyday training. The engineered mesh upper keeps feet comfortable, cool, and fresh on long runs with strategically placed perforations for airflow. Its seamless structure reduces chafing and irritation, while the stretchy design offers a perfect, natural fit. A soft tongue and cushioned collar ensure a secure, irritation-free feel, complemented by traditional laces for midfoot lockdown. The midsole features a double-layer design with incrediRUN foam and a PWRRUN layer for high-performance training. incrediRUN provides exceptional cushioning and rebound, while the durable PWRRUN layer ensures stability and an energy-efficient platform with shock-absorbing properties. A 3/4-length carbon fibre plate enhances toe-off and smooth landings, working with Speedroll Technology to propel you forward with less effort. The XT-900 carbon rubber outsole offers optimum grip, traction, and support on various surfaces, with strategically placed rubber in high-wear areas for enhanced longevity and grip.
