The Saucony Endorphin Pro 5 is the latest generation of the acclaimed Endorphin Pro carbon-plated racing series, purpose-built for race day and high-performance speed training. It features a new PWRRUN HG supercritical Pebax foam midsole that delivers significantly improved energy return over its predecessor. Combined with a full-length carbon fiber plate and the SpeedRoll rocker geometry, it provides a smooth yet explosive propulsive feel. The 28mm forefoot and 36mm heel stack height (8mm drop) balances impact protection with responsive ground feel. At approximately 205g (men's US9), it achieves race-level lightweight standards. The upper uses a thin, breathable woven mesh with a lockdown lacing system for a secure fit. The outsole places rubber strategically to minimize weight. The Pro 5 continues the Endorphin Pro legacy as a top choice for serious runners on race day.
