THIS WOMEN'S SHOE IS FOR: The Launch GTS 8 is for runners who want a lightweight shoe with a fast, fun ride plus trusted GuideRails support. Durable enough for training but light enough for race day, the Launch GTS 8 is designed to keep up on every run. Predecessor: Brooks Ravenna 11. MAXIMUM SUPPORT: The Launch GTS 8 is the more supportive version of the Launch 8. The integrated GuideRails holistic support system keeps excess movement in check to keep you moving comfortably and providing support beyond just the feet, to the most injury-prone part of a runner’s body: the knees. LIGHTWEIGHT CUSHIONING: Brooks lightest BioMoGo DNA midsole cushioning provides a fast and supportive ride without the extra weight - perfect for days when you are working on your speed. BREATHABLE AND SLEEK FIT: The new one-piece mesh upper creates a closer-to-foot-feel that is more breathable than ever before. QUICK TRANSITIONS: The Midfoot Transition Zone is shaped to go from heel to toe quickly. Newly added blown rubber in the forefoot propels you forward for a faster ride.
