The Adidas Adizero Triple Jump 2 Spikes feature a technical Coolever fabric lining. The clover-shaped construction of the yarn keeps your foot at an optimal temperature whilst drawing moisture away from the skin to keep you comfortable. To keep you quick with no distractions or restrictions, the upper of the shoe is engineered with a welded, stitchless composite membrane, with a suede inner frame and a sprint web overlay. This extremely lightweight upper which surrounds the shoe provides great breathability as well as being completely secure. A foam insole provides optimal comfort.
