Men's Valkyrie Speedworks
The Men's Valkyrie Speedworks Runner is TYR's fast-training daily runner — built for athletes who want race-day responsiveness in a shoe they can run in every day. The LaunchPX Midsole is constructed from 100% Pebax® supercritical foam, delivering maximum energy return, responsive cushioning at every stride, and consistent performance mile after mile. The Nylon PowerPlate runs the full length of the shoe, providing responsive energy return and smoother stride transitions without the stiffness of a full carbon plate — making the Speedworks the ideal choice for fast-paced training, tempo runs, and long-distance efforts. The Alphaweave Upper is engineered for breathability, reducing foot heat buildup and delivering an adaptive, featherlight fit over distance.
