The Endorphin Pro uses a carbon fibre plate within PWRRUN PB foam — Saucony's racing formulation. At race pace, the carbon plate creates propulsive energy return that nylon cannot replicate.
For runners who race half or full marathons with performance goals, the shoe's design is appropriate to the task. Carbon-plate shoes do not make slow runners fast, but they reduce energy cost at race effort — which matters for runners pushing at the edge of their capability.
Beginners. Runners racing shorter distances where carbon gains are marginal. Runners who want a training shoe — the Pro is not designed for daily training miles.
