The Endorphin Speed 5 is the 5th iteration from the Saucony Endorphin family. It's a race-day shoe made for speed with a new lightweight engineered mesh that's ideal for fast-paced runs up to marathon distances. 

Version 5 has a re-engineered winged nylon plate and reworked outsole with expanded coverage in the heel for durability. The midsole foam is made with two layers of PWRRUN PB foam, creating a lightweight and responsive midsole with exceptional energy return.

This Boston Edition draws inspiration from the city’s transit system, featuring bold, energetic colour blocking to celebrate the iconic marathon city.
