Adrenaline GTS 21 Grey Running Shoes

The smooth transition DNA Loft goes beyond the heel, all the way to the forefoot for a smooth buttery ride. The GuideRails holistic support system is an innovative technology that supports your body in its natural motion path while keeping excess movement in check. The newly engineered air mesh upper hugs the foot for a secure fit while also improving breathability. The DNA Loft cushioning extends throughout the midsole for a smoother transition from heel to toe. The 3D Fit Print applies strategic stretch and structure to the upper.
