The Asics Gel 1140 is the very latest version of the 1000 series which has just got lighter. The Men's Asics Gel 1140 is perfect for mild over-pronators who run long distances, including 10k and marathons as well as road runners and on treadmills. Asics Gel 1140 contains a smaller midsole segment than the Asics Gel 2140 providing milder support. Space Trusstic is newly engineered for softer more lightweight midfoot stability. Most noticeably with the new Asics Gel 1140 is the fit around the heel collar reduced in circumference to allow better ankle fit. Additionally the more open toe-box lets the foot spread out more in propulsion.
