Soft AMPLIFOAM cushioning in the midsole adapts to the pressure during take-off and landing GEL technology in the rearfoot reduces pressure in the heel No-sew and stitch-down design increases durability and supports the natural movement of the foot Gusseted tongue reflects debris and dirt that's kicked-up Whether you're training for an off-road marathon or are looking for a lightweight alternative for walking boots, the GEL-SONOMA 7 from ASICS has been designed to conquer uneven terrain when your run takes an unexpected turn off the beaten path. Offering ample shock reduction between strides, the trail-specific outsole increases your grip on loamy and uneven surfaces. Plus, the gusseted tongue at the front helps deflect debris when you're on the move; handy if you're not a fan of having stones stuck in your shoes. GEL Cushioning TechnologyFeaturing updated GEL technology, the GEL-SONOMA 6 improves on its predecessor by softening the foam section in the heel for improved comfort and shock absorption. In reducing the pressure on the balls of the heel and cushioning shock impact, you're putting less stress on the muscles, pushing beyond the finish line just that little bit further every time. AmpliFoam MidsoleComfort hasn't been isolated to just the heel either. ASICS Amplifoam in the midsole offers soft cushioning at a lower density, meaning you're experiencing a softer foot strike through every mile. Designed to deliver flexibility, comfort and adaptability, it encourages your muscles to work harder by deforming quickly under pressure and returning to shape quickly.
