Saucony Endorphin Speed 4 Running Shoes

Speed, performance and comfort combine in the Endorphin Speed 4, designed to get you over the finish line faster than ever before.

Lightweight Breathable Mesh Upper

Designed to provide lightweight, breathable support, the Saucony Endorphin Speed 4 has been constructed using a zonal-engineered mesh upper. This upper has been fully redesigned to deliver a comfortable fit from heel to toe whilst still providing lightweight breathability and comfort. The minimal, engineered mesh will encase each foot in breathable comfort. The perforated mesh allows cool air to flow throughout the shoe to remove an uncomfortable heat build-up so you can remain cool, dry and comfortable at all times. The mesh acts as a lightweight second skin that creates a perfect microclimate for your feet to thrive in. As well as this, FORMFIT technology surrounds the foot in a made-for-me feel which accommodates the feet, giving them a feeling like these shoes were made specifically for you. Completing the upper is a lacing system which locks down the midfoot to reduce in-shoe slippage so you can enjoy distraction-free strides.

PWRRUN PB Foam Midsole

The Endorphin Speed has been constructed using Saucony's signature ultralight and springy PWRRUN PB cushioning. PWRRUN PB provides lightweight and springy cushioning to keep your feet comfortable at all times. The lightweight cushioning provides a soft and stable base underfoot that gives you an added spring in your step as you move through the gait cycle. Working with PWRRUN PB is Saucony's signature ultralight composite plate which ensures powerful transitions. This updated version has been designed with a winged Nylon plate to supply energy return and better support through your daily training. The plate provides maximum Speedroll that propels you forward, creating a feeling of continuous momentum so you can run faster, not harder. This revolutionary technology supports your foot as you move through the gait cycle and propels you forward at toe-off for more dynamic strides. By combining elevated cushioning and a stiff forefoot, the midsole ensures an instantly responsive ride from the moment you put them on till the moment you take them off. The new SRS sockliner combines EVA and PB for structure.

XT-900 Outsole

Developed to be hardwearing and grippy, the outsole of the Endorphin Speed has been constructed using XT-900, a durable rubber outsole. This premium outsole offers exceptional traction and durability so you can continue with complete confidence. The rubber is able to form a solid connection with a wide range of different surfaces, which will give you one less thing to worry about. The strong connection with the ground will also provide a firm base for you to push off from, making your gait cycle more efficient. Reinforced in high-wear areas the outsole will withstand long-lasting wear. Lastly, multi-directional grooves are placed strategically to further secure your feet to the ground, and will also improve efficiency in takeoffs, landings and changes of direction.
