What Our Gearhead(R) Experts Are Saying:"What sets the Endorphin Pro 5 apart is how powerful yet controlled the ride feels. The combo of PWRRUN HG and PWRRUN PB foam gives it that springy, race-day energy, and the new carbon plate feels smoother and more aggressive when accelerating. The grip from the PWRTAC outsole is also impressive when pushing through tight corners or wet pavement."The Saucony Endorphin Pro 5 Running Shoe brings race-focused engineering to long-distance efforts and fast training days. Built to help us chase PRs, its energetic superfoam midsole and tuned carbon plate deliver the snappy response needed when the pace climbs and staying efficient matters most. Saucony pairs a PWRRUN PB base with a super-critical PWRRUN HG top layer for exceptional rebound, giving each stride a buoyant, lively feel. The redesigned carbon fiber plate sharpens transitions with a smooth, aggressive roll, while PWRTAC rubber enhances traction and durability across varied road conditions. Lightweight materials, breathable support, and refined geometry come together to create a shoe built for pure speed.
