Check your Endorphin Speed 5 →Reviewers note improved outsole coverage and robust build quality, with no major early wear issues reported. The PWRRUN PB foam and new upper materials are expected to last as long as or longer than previous versions. While long-term data is still accumulating, early feedback from testers and users suggests above-average durability for a lightweight trainer/racer.
The Saucony Endorphin Speed 5 is widely praised by experts and users for its versatility, excelling especially at tempo paces and structured workouts due to its lightweight build, responsive PWRRUN PB midsole, and nylon plate, which provide a snappy yet cushioned ride. It is also highly suitable for daily training and long runs, as the updated foam and slightly softer ride make it comfortable for extended efforts without excessive firmness or instability. The shoe is considered a strong option for racing, particularly for runners who prefer a more stable, less aggressive alternative to carbon-plated super shoes, though it may not match the absolute top-end performance of dedicated race models. Its moderate support and smooth transitions make it accessible for a wide range of paces, but it is not designed for trail running due to limited traction and lack of protection for technical terrain. For recovery runs, it is adequate but not ideal, as some runners may prefer a softer, more plush shoe for easy days.
Ideal for Best suited for intermediate to advanced runners who value versatility and want a single shoe for speedwork, long runs, and occasional racing. Ideal for those with a neutral gait who appreciate a lively, moderately cushioned ride and need a shoe that transitions smoothly between training intensities.
The Endorphin Speed 5 refines the fit with a more breathable and comfortable upper, improved heel lockdown, and a slightly roomier toebox. The shoe maintains a performance fit but is more accommodating for a wider range of foot shapes. The ride is softer and less stiff than previous versions, with a smoother transition and more medial guidance, making it suitable for both speedwork and longer runs.
Sizing: Generally true to size; redesigned upper offers a more secure fit with a slightly wider toebox compared to previous versions. Most testers recommend sticking with your usual running shoe size, especially if you wore the Endorphin Speed 4. No widespread advice to size up or down.
