Get ready for your next half-marathon in the new, lighter GT-1000. Support, comfort and cushioning, this one has it all in abundance.       The GT-1000 feels like an extension of your leg. By using fewer layers, the lightweight upper effectively hugs your foot and feels just like a second skin.  Stabilising technology stops your foot rolling inwards too much, giving greater comfort and endurance.                                                                                                                                                                       The full engineered mesh upper construction on the next generation GT-1000 ensures a better fit and modern good looks. The Duomax – a proprietary ASICS system that consists of two different density midsole materials – is designed to provide smooth over pronation control. The supreme midsole material, SpEVA improves bounce-back characteristics and decreases midsole breakdown.
