Men's Saucony Endorphin Speed 4 Boston Edition 2025

A Versatile Running Shoe With Boston Flare

The Saucony Endorphin Speed series has dominated the space as one of the most versatile and lightweight trainers you can find. The Endorphin Speed 4 continues this legacy with a few adjustments and upgrades to help push this shoe to its limits.

A familiar feeling of PWRRUN PB can be found underfoot, creating a soft but super-responsive experience that’s further enhanced with the addition of the new Super Responsive sockliner. Within this premium midsole cushioning is an updated winged nylon plate, creating torsional rigidity while allowing forefoot flexibility. All these features underfoot synergize with incorporated SPEEDROLL Technology to bring you an efficient stride with effortless speed.

Run with confidence with the secure-fitting, engineered zonal mesh upper, offering optimal breathability with minimal weight. The Endorphine Speed 4 upper uses an integrated tongue to increase comfort and create a better fit. Along the outsole, you’ll notice a distinct lattice configuration made from Saucony’s XT-900 carbon rubber. The combination of premium material and expert design gives this trainer enhanced durability and incredible traction on varied surfaces.

The Saucony Endorphin Speed has built a loyal fanbase over the years and there doesn’t seem to be any sign of that stopping soon. Get this limited edition version created for The Boston Marathon® while supplies last.
