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 a structured design and strategically placed perforations for constant airflow. Seamless construction reduces chafing and irritation, while the stretchy material offers a perfect fit and feel, encouraging natural foot movement. A soft tongue and cushioned collar provide a secure, irritation-free fit, complemented by traditional laces for midfoot lockdown. The cutting-edge, double-layer midsole pairs incrediRUN foam with a PWRRUN layer for high-performance training. incrediRUN is Saucony's lightest and most responsive midsole compound, offering outstanding cushioning and exceptional rebound. The durable bottom PWRRUN layer ensures stability and an energy-efficient platform with shock-absorbing properties to reduce injury risk on tough surfaces. A 3/4-length carbon fibre plate enhances toe-off and provides smooth landings, working with Speedroll Technology to propel you forward with smooth heel-to-toe transitions. The XT-900 carbon rubber outsole ensures optimum grip, traction, and support on road and rough surfaces. Durable rubber is strategically placed in high-wear areas for longevity and reliable grip, forming a solid connection with the ground for a firm landing base and enhanced strides.
