Pick up the pace with a race-ready shoe from Saucony's Endorphin collection, performance engineered to give you an effortless feeling of top speed. The secret to this smooth forward momentum is Saucony's SPEEDROLL Technology. A combination of stack heights, midsole shape and material gets you from heel-strike to toe-off with ease. Your stride is amplified and your pace improved with the incredible energy return from every step. Of the three models in Saucony's performance range, the Endorphin Speed is your crossover train/race shoe. Its snug fit locks you in come race day, while the ultralight PWRRUN foam is soft and responsive enough to keep you comfortable on those long training runs. The signature S-curve carbon-fibre plate of the Endorphin Pro makes for powerful transitions, giving you the edge in competitions. For the ultimate in training comfort, the Endorphin Shift's springy support and cushioned fit provide a plush ride for running on roads.
