We designed the Triumph 23 for those who want to run longer. The softer, lighter PWRRUN PB midsole—now with more cushioning—delivers a responsive ride that can power you through. It's paired with a premium, super-responsive sockliner (SRS) and an updated outsole, giving you smooth, flexible transitions mile after mile. Whether it’s a slow long run or jumping in a weekend 5K, this shoe will push your comfort zone with every step.
