Saucony Endorphin Pro 4 Running Shoes: Push it to the next level with PWRRUN PB and PWRRUN HG for propulsive movement and a snappy Carbon plate for responsive speed. The lightweight, breathable mesh upper is engineered for support, ventilation, and comfort, allowing air to flow to keep you cool, dry, and comfortable. A silky smooth heel liner, integrated tongue, and traditional lacing system provide a comfortable, sock-like feel, making you race-ready. The PWRRUN PB midsole offers super-responsive shock dampening and lightweight, springy cushioning, perfect for personal bests. This foam is 40% lighter than its predecessor, minimizing weight for faster, steadier running. Sandwiched between two layers of ultra-resilient, extra-soft PWRRUN PB Foam, the Carbon-fibre plate ensures powerful transitions and fuels every stride. SPEEDROLL technology propels you forward effortlessly at toe-off for a more dynamic run, allowing you to run faster, not harder. The top of the midsole features PWRRUN HG technology for lightweight, springy cushioning with more rebound than previous PWRRUN foams, enabling you to achieve your new PB. The combination of foams delivers maximum bounce and cushioning. The XT-900 Outsole provides control on the track with a solid connection to the ground for an efficient gait cycle. The chevron tread pattern offers traction on wet pavement and compact dirt, allowing the sole to flex for fluid movement. Reinforced high-abrasion zones ensure optimal traction and durability.
