Fast. Responsive. Smooth. Now in a Wide Fit.

The Saucony Endorphin Speed 5 Wide is built for runners who want speed without sacrificing comfort or versatility.

Designed for speed sessions, tempo runs and race day, it combines lightweight PWRRUN PB cushioning with a newly designed semi-rigid nylon plate to create a responsive, snappy ride that still feels more forgiving than a traditional carbon-plated racing shoe.

Saucony’s SPEEDROLL technology helps encourage smooth forward transitions, while the updated engineered mesh upper provides a lightweight, breathable fit. This Wide version gives runners additional room through the shoe while retaining the fast, performance-focused feel of the Endorphin Speed 5.

Cushioning & ride

The Endorphin Speed 5 uses PWRRUN PB, Saucony’s lightweight PEBA-based performance foam.

Two layers of PWRRUN PB surround a full-length semi-rigid nylon plate, creating a balance of cushioning, responsiveness and propulsion.

Compared with a rigid carbon plate, the nylon plate offers a slightly more forgiving feel, helping make the Speed 5 versatile enough for both structured training and racing.

SPEEDROLL technology

Saucony’s SPEEDROLL geometry is designed to help move you smoothly through your stride.

The curved underfoot shape works together with the responsive foam and plate to encourage quicker transitions from foot strike through toe-off, particularly when the pace increases.

Wide fit

This model is the Wide version of the Endorphin Speed 5.

It is designed for runners who need additional width while still wanting a lightweight, performance-focused shoe for faster running.

For runners with a broader forefoot or those who find standard-width speed shoes too restrictive, the Wide Endorphin Speed 5 can offer a more accommodating alternative.

Updated upper

A lightweight engineered mesh upper provides breathability and a secure performance fit.

The updated construction is designed to remain comfortable during faster sessions while keeping unnecessary weight to a minimum.

Outsole & durability

The outsole has been reconfigured with expanded rubber coverage through the heel to improve durability.

A full-length groove through the outsole also helps support a smoother transition through the gait cycle from landing to push-off.

Who is the Endorphin Speed 5 Wide for?

The Endorphin Speed 5 Wide is a great option for runners who want one fast shoe that can handle both training and racing.

Its combination of PWRRUN PB foam, nylon plating and SPEEDROLL geometry gives it plenty of pace when you want to push, while the more forgiving plate construction makes it practical for regular speed sessions rather than saving it only for race day.
