The Valkyrie Speedworks Runner is TYR’s impressive introduction into the training shoe world. It is the ultimate running shoe that has been thoughtfully engineered to support you with every stride. This nimble trainer has all the features to propel you forward for miles: a lightweight mesh upper, the full length nylon plate surrounded by Pebax® foam, TYR’s signature anatomical toe box and a rubber outsole for traction on the road. Whether you are approaching your first big race or looking to explore a new running route, the Valkyrie Speedworks provides excellent impact absorption at a variety of paces. This TYR shoe is bouncy without being too pillowy—and becomes even springier the faster you go. Details Upper: The Alphaweave upper is super airy, making it your ideal material for extended runs. This mesh construction is breathable yet forgiving, with the lockdown reinforcement panelling providing extra security. The locking laces give you a stable feel while running, and the light padding on the gusseted tongue and heel cup add comfort. Midsole: The LaunchPX midsole is where the magic happens. A full length nylon plate is sandwiched between layers of 100% Pebax® supercritical foam. The nylon plate enhances the shoe’s support on your cushioned ride. The beaded foam layers provide ultimate responsiveness and comfort at any speed. Outsole: The outsole’s rubber is concentrated on the forefoot to give you traction on your footstrike. The channels of rubber expose the midsole foam and a portion of the nylon plate.
