Puma XT S Trinomic Mens Trainers / Shoes - Back in the '90s, PUMA hit the running shoe scene with Trinomic technology: clear rubber cells that collapsed and rebounded for cushioning and support. Today, they have revamped the vintage Trinomic silhouettes for everyday comfort and style, keeping that throwback technology intact. New to the Trinomic family, The XT S. It's got all the usual goods (lightweight mesh upper, chunky cushioned midsole) but we threw in a few perks...including a sleek, one-piece upper, and transparent tooling at the insole so the Trinomic tech is visible from inside the shoe.Mesh upperLace closure for a snug fit. Midsole featuring throwback PUMA Trinomic technology: rubber cells that collapse and rebound for cushioning, stability, and motion control. Rubber outsole for grip. PUMA Formstrip at lateral and medial sides. PUMA Logo at tongue; PUMA Cat Logo at heel.
