The Saucony Womens Endorphin Speed 4 is a highly versatile trainer, perfect for everything from long-distance runs to personal bests and races. It combines exceptional comfort and durability, making it a favourite among tempo runners. The midsole features a blend of three key technologies: PWRRUN PB foam for a bouncy, lightweight feel, a winged nylon plate for a combination of forefoot flexibility and vertical firmness, and Speedroll technology for smooth transitions from landing to toe-off, resulting in an easier stride. Weight: 206g, Stack height: 36-28mm, Offset: 8mm. This style is vegan and contains recycled materials. It offers smooth SPEEDROLL technology for effortless speed and forward motion. The PWRRUN PB foam provides a balanced feel that is firm enough for propulsion yet soft enough for cushioning. The re-engineered winged nylon plate adds vertical reinforcement while maintaining forefoot flexibility. The shoe also features a Super Responsive Sockliner (SRS).
