Don't let Jack Frost obscure your running ambitions. With the Asics GT 1000 4 G TX Running Shoe for Men, cold weather running just got a whole lot easier. Crafted for slushy romps through the park or Saturday interval sessions, the GT 1000 4 G TX is a necessary arrow in your winter wear quiver. The waterproof, breathable Gore Tex upper provides unparalleled protection while the Impact Guidance System enhances your foot's natural gait from heel strike to toe off. The Guidance line works with the Guidance Trusstic System to fix overpronation problems. This year's edition is outfitted with a new Snow Rubber Compound, great for taking on that slightly gnarly icy pulp. Additionally, Asics integrated many layers at the midsole for a fully cushioned run. Gel cushioning systems cover the rearfoot and forefoot to attenuate shock, and SpEVA helps the GT 1000 bounce back after each step. Duomax's support system inserts a dual density midsole for support and stability.
