Features Comparison:


The Triumph 21 is Constructed with an engineered mesh upper to facilitate airflow and drainage with printed overlays reducing irritation inside the shoe. The outsole leverages durable carbon rubber XT-900 strategically placed to protect high-wear zones enabling hundreds of miles.

Carved articulation through the center enhances natural flexibility. The PWRRUN+ midsole cushioning handles easy runs or long mileage absorbing shock and rebounding with consistent soft responsiveness.

The Endorphin Speed 4 also utilizes robust carbon rubber on the outsole heel but complements crystal rubber lugs upfront for slick traction when racing in wet conditions. At its core is a propulsion plate embedded within responsive PWRRUN PB foam.

This compress-then catapults system tunes a snappy ride. A new zonal mesh wraps the upper fitting securely while upping breathable comfort, especially over warmer miles.


The outsoles on both the Triumph 21 and Endorphin Speed 4 utilize durable carbon XT-900 rubber in high-wear areas, so they can handle hundreds of miles of training without significant wear.

The Endorphin’s midsole foam may compress slightly over time, losing some bounce. But the Triumph’s thicker midsole will retain cushioning longer. Both have mesh uppers that resist debris well, though the Triumph’s sturdier upper likely wins in longevity.


The Triumph 21 fits true to size for most runners according to the vast majority or wearer reviews. It incorporates a wider toe box design to allows natural toe splay and relaxation during runs rather than squeezing feet.

This roomier fit makes runs more comfortable for many. As a neutral model, the Triumph 21 runs best for runners with medium to high arch types in particular.

Meanwhile, the Endorphin Speed 4 unfortunately does run small by around a 1/2 size according to numerous reports. Considering sizing up or trying shoes on in-store is wise for this model.

The Speed 4 fits runnners with medium arches the most ideally, though some testers still find the toe box area too constricting even when properly sized up. Using the integrated tongue and fiddling with laces tensions can help dial in comfort and security on feet for some.


With a 10mm drop and no stability features, the Triumph 21 suits neutral runners best. The dual-density midsole of the Endorphin Speed 4 makes it moderately stable for neutral runners.

Flared heels and a mild medial post offer light guidance for mild overpronators as well. Both shoes will keep neutral runners feeling secure via their supportive uppers.


The standout feature of the Triumph 21 is its high-level cushioning from the PWRUN+ foam – perfect for easy long-distance training. An ample 32mm/22mm of cushion absorbs impact well with lots of bounce.

The Endorphin Speed’s stack height of 30.5mm/22.5mm puts it in the lower cushion category, but the PWRRUN PB foam has just enough softness to take the edge off hard surfaces and provides responsive cushioning better suited to uptempo running and faster paces.


With a $160 price tag, the Triumph 21 offers excellent value as a daily trainer with premium cushioning, support, and durability. It provides responsive comfort for logging daily miles without breaking the bank.

In contrast, the $227 Endorphin Speed 4 costs more but delivers energetic performance perfect for faster training and race day with its lightweight build, reactive foam and propulsion plate. The Speed justifies its higher price with speed-focused tech.

Ultimately, both shoes provide quality and features that match their intended purpose – the Triumph 21 for daily miles and the Speed for faster sessions and racing. Their pricing aligns with the performance and value each delivers.

Performance Comparision:

For Walking:

The Triumph 21’s plush cushioning comfort adapts well to hiking and walking longer distances. The wide toe box allows toes to relax while the soft upper won’t rub uncomfortably.

Together with the flexible sole, the Triumph makes walking feel easy. While the Endorphin Speed 4 can handle casual walks fine, its snugger fit isn’t ideal for hours of walking and less cushioning causes foot fatigue sooner.

For Running:

As daily trainers designed for moderate paces and longer miles, the Triumph 21 excels at daily runs. Runners stay comfortable mile after mile thanks to durable cushioning.

Meanwhile, the Endorphin Speed 4 matches the versatile performance to its name – nailing everything from tempo runs to races with snappy energy return from its responsive foam and propulsion plate. For varied training needs, it’s a strong choice.

For Plantar Fasciitis:

With ample high-cushioning foam underfoot, the Triumph 21 makes an excellent choice for runners dealing with plantar fasciitis inflammation and heel pain. Impact protection and bounce relieve pressure well, while the spacious toe box avoids compressing feet. The Endorphin Speed 4 would not be suggested for PF; its thinner foam exposes aggravated heels.

For Standing All Day:

Due to its spacious fit and plush cushioning, the Triumph 21 is also suitable for jobs that require lots of standing. Feet and joints feel fresh even after hours of wear.

However, the snug low-drop Endorphin Speed 4 isn’t a practical all-day shoe because of its tighter instep and thinner midsole. Standing for extended periods will quickly become uncomfortable compared to appropriate work shoes.

final Verdict:

In conclusion, when judging between the Triumph 21 versus the Endorphin Speed 4, the winner ultimately comes does to the individual runner, their biomechanics, and training needs.

The Triumph 21 dominates as an ultra-cushioned long run and recovery day shoe. With CloudTec cushioning underfoot, it can also tackle walking or jobs with long hours on your feet.

Meanwhile, the Endorphin Speed 4 claims victory as a light, responsive, durable shoe ideal for tempo days, long intervals, or race efforts up to a half marathon. Consider your personal fit preferences, footwear priorities, and running plans to pick the best Saucony shoe.
