Saucony Endorphin Trainer Shoes: Lightness and Speed in Your Training. These shoes are ideal for runners looking to combine speed and comfort in high-mileage daily training. They are designed for asphalt surfaces and are a neutral shoe type, perfect for training. The shoes weigh 280g and have an 8mm drop (41mm heel/33mm midfoot). They feature a 3/4-length carbon fiber plate, grooved for better take-off and smooth landings, and offer PWRRUN / incrediRUN cushioning. They are also vegan and made with recycled materials. Expanding the Endorphin franchise, these high-tech shoes are built for runners who demand both speed and durability, bringing race-day innovation to everyday training. The engineered mesh upper keeps feet comfortable, cool, and fresh on long runs with strategically placed perforations for constant airflow. The seamless structure reduces chafing and irritation, while the stretchy design offers a perfect fit and feel. A soft tongue and cushioned collar provide a secure, irritation-free fit, and traditional laces lockdown the midfoot for stability. The innovative 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. The 3/4-length carbon fibre plate enhances toe-off and provides smooth landings, working with Speedroll Technology to propel you forward. The XT-900 carbon rubber outsole ensures optimum grip, traction, and support on road running and rough surfaces, with strategically placed durable rubber in high-wear areas for longevity and reliability.
