The upper has been reimagined with a new engineered mesh that adjusts to your foot's natural shape while providing a comfortable midfoot hold. Constructed using a breathable mesh, the ASICS GT-1000 11 Running Shoes encase each foot in comfort. The mesh allows air to fully permeate the entire upper, providing a constant supply of fresh, cool air while simultaneously forcing out hot, muggy air. The mesh upper creates a perfect microclimate for your feet to thrive in. Overlays have been used on the upper to increase structure and support. The overlays have been placed around the midfoot and the toe for long-lasting comfort and guidance. An OrthoLite X-30 sock liner provides soft step-in comfort. Completing the upper is a lacing system that locks down the midfoot to reduce in-shoe slippage for a distraction-free fit.
