Saucony Triumph 21 vs Triumph 20: A Familiar Cushioning Favourite Gets a New Upper

Introduction

The Saucony Triumph 21 arrives as one of the most anticipated cushioned trainers of the season, and the early signs are reassuringly familiar. At $160, with a men’s size 8 weighing 280 grams (9.9 ounces) and a 10mm drop, it carries forward the same midsole recipe that made its predecessor a standout. The headline changes sit almost entirely in the upper: a revamped flat knit material for improved fit and breathability, a modified lacing system for better lockdown, a heel lock design, and a rear pull tab for easier on-and-off.

The bigger question for buyers is whether the update justifies switching from the Triumph 20, a shoe that topped our cushion shoe picks for the past year. This comparison breaks down what has changed, what has not, and which shoe makes more sense depending on your budget.

What’s New in the Triumph 21

The updates over the Triumph 20 are concentrated in the upper. The previous version used a soft dual-layer material, while the 21 moves to a one-piece flat knit fabric with lots of breathability built in. On a warm 21-degree day, the shoe felt light and airy on foot, without the heavy, chunky feeling you might expect from a max-cushion trainer.

The lacing system has also been reworked for lockdown, and there is generous padding around the tongue and ankle collar. A heel lock section holds the foot securely in place, and a pull tab at the rear makes the shoe easy to pull on and off. Neither change felt dramatic in practice, but neither is a step backwards either.

Underneath, nothing has changed. The PWRRUN+ cushioning in the midsole and sock liner is identical to the Triumph 20, and the outsole carries the same generous rubber coverage that made the previous model so impressive for grip and durability.

Fit and Comfort

Fit runs true to size, and this is a very comfortable shoe. The Triumph line has always been easy to live with, and the 21 continues that. There is a noticeable amount of room in the forefoot and a little extra space in front of the toes, so runners with genuinely narrow feet may find it slightly loose. For everyone else, it should not be enough to warrant sizing down.

The lockdown from the new lacing system is easy to dial in, padding around the tongue and collar adds to the plush feel, and the heel holds firmly without any slipping. Across a demanding first run, there were no comfort issues at all.

Ride Performance: Easy Runs to Faster Work

This is where the Triumph line earns its reputation. The PWRRUN+ midsole is one of the best foams available in a heavily cushioned shoe: nicely soft without feeling mushy, but with a distinct pop and energy return that pushes you forward more than most max-cushion shoes manage.

On an endurance test session that included a 20-minute threshold effort, reps at 10K pace, and short 5K-pace intervals, the shoe handled far more than its cushioned category would suggest. Easy and long runs feel genuinely enjoyable, threshold pace felt great, and even 5K pace around 3:45 per kilometre felt fine, if not ideal. It never felt heavy or clunky.

The outsole deserves mention too. With plenty of rubber protecting the foam, it feels protective and grippy across varied road conditions. Wet-road testing was not possible in this first run, but given the outsole matches the Triumph 20, which impressed in that regard, expectations are high.

Where the Triumph 21 Fits Your Running

The Triumph line is increasingly best described as a max-cushion daily trainer rather than a pure slow-run shoe. It skews toward daily training, easy runs and long runs, but it has enough versatility to cover faster sessions and even carry you through a half marathon or marathon. If you want one shoe that can do a lot of different runs, including on holiday or as a single-shoe rotation, it is a strong candidate. That versatility separates it from cushioned trainers that are best reserved for easy mileage only.

Buying Advice: Which One Should You Get?

Here is the honest takeaway: the Triumph 21 is a very minimal update, and on a first run it is hard to notice a meaningful difference from the Triumph 20. The upper changes are real and welcome, but the ride is much of the same.

Because the Triumph 20 was already one of the best cushioned shoes available, the practical advice is straightforward. If you can find the Triumph 20 at a discount, you are probably not losing much by choosing it over the 21, and it may not be worth paying more for the newer version. If you are buying fresh and want the latest upper and lacing refinements, the 21 is an excellent pick at its price point.

Conclusion

The Saucony Triumph 21 is a solid, enjoyable continuation of a much-loved line. It keeps the superb PWRRUN+ cushioning, versatile ride and excellent outsole that made the Triumph 20 a favourite, while refreshing the upper with breathable flat knit material, a modified lacing system and a secure heel lock. Nothing here changes the shoe’s character, and that is largely the point: if the Triumph 20 was already at the top of your shortlist, the 21 simply keeps it there. The smart move for value-focused runners is to compare current pricing on both versions and pick whichever is cheaper.
