We now have information on the new version of one of the most versatile models on the market. Saucony Endorphin Speed 5 They arrive in June 2025 with an update that improves key points without losing the essence of what made them so popular: speed, versatility and a pleasant yet dynamic feel.
Thinner, breathable and adaptable upper
One of the big new features comes in the upper. Saucony is betting on a engineered mesh lighter and more airy, which significantly improves breathability compared to the Speed 4. The feeling when wearing them is fresher and more snug, with an interior that adapts to the foot without pressure and with that touch of elasticity that is appreciated on long runs or hot days.

Midsole unchanged... but with more sparkle
The successful combination of PWRUN PB and nylon plate throughout the midsole, maintaining the formula that has given this shoe a well-deserved reputation among those looking for a versatile option for quick training sessions or even competitions.
Of course, there are subtle changes that improve the experience. One of them is the complete longitudinal groove, which runs across the entire sole and provides a smoother transition from contact to take-off. In addition, a rigid piece in the midfoot, which provides greater lateral stability without compromising forefoot flexibility.

Redesigned plate: less wing, more control
One of the most significant changes is the new nylon plate. To give you an idea, the old one had two lateral wings in the midsole area that slightly protruded from the midsole. In the updated version, Endorphin Speed 5 maintains that wing in the inner area but the outer area is reduced. In addition to being a very flexible plate, we find a localized stiffness in the midfoot, seeking better motion control without sacrificing propulsion efficiency. This adjustment improves cornering feel and offers a slightly more stable ride compared to the previous version.
More robust and functional sole
The sole has been Reconfigured with increased rubber coverage on the heel, which increases durability and offers better traction for longer periods of time or at medium speeds. The tread patterns have also been modified to improve grip on different surfaces.
