The Launch GTS 9 is for runners who want to go consistently fast and enjoy a responsive, lightweight shoe that offers added support. GREAT SUPPORT: The Launch GTS 9 is the more supportive version of the Launch 9. The integrated GuideRails holistic support system keeps excess movement in check to keep you moving comfortably while providing support to your feet, knees, and hips. ENHANCED BREATHABILITY: Reengineered upper features Creel Warp mesh, designed to be extremely lightweight and breathable. Hints of reflectivity on the upper to increase visibility on the road. LIGHTWEIGHT CUSHIONING: We have added more BioMoGo DNA cushioning to the midsole for an even faster ride without the extra weight. A dynamically responsive ride for days when you are working on your speed. RESPONSIVE TRANSITIONS: Redesigned midsole increased by 2 mm to provide runners with more responsiveness while the Green Rubber Outsole helps your foot move quickly from heel to toe.
