The shiny new GT 2000 3 Men's Trail Running Shoe is the lightest in the history of Asics's 20 year old GT 2000 series, at just 10. 7 ounces, but it's far more than just a lightweight kick. It has support oozing out of its mesh and synthetic upper, from the high energy cushioning of the FluidRide midsole to the stability support of the Dynamic DuoMax support system. GEL Cushioning in the rearfoot and forefoot disperses shock during impact and toe off, and the GT 2000's Impact Guidance System ensures that every component of the shoe is designed to work in concert, so each part of the design helps you achieve a smooth, natural gait. The GT 2000 also features Asics' Guidance Trusstic System, a plastic band on the outsole that helps channel impacts into forward energy to keep you cruising with every stride. Asics' Guidance Line helps you achieve a smooth, efficient foot roll, and the Heel Clutching System uses an exoskeletal heel counter to keep your foot locked solidly in place to increase comfort and prevent blisters. The finishing touch is the ComforDry Sockliner, which provides a snug fit, moisture wicking capabilities, and antimicrobial properties to keep your feet smelling fresh.
