Built for speed, the Brooks Launch GTS 9 is lightweight and versatile to get you across the finish line faster. The Brooks Launch GTS 9 features Brookrsquos holistic GuideRailsreg support system that keeps excess movement in check while supporting your body during its natural motion path. Brooks redesigned the Launch GTS 9 by adding an additional 2mm of their lightweight BioMoGo DNA foam to the midsole for a fast, dependable ride. In addition to the redesigned midsole, a new Green Rubber Outsole will help your foot transition quickly from the heel to toe. The new Creel Wrap mesh upper is both lightweight and breathable to give you a comfortable fit every time you lace up. Plus, Brooks added hints of reflectivity to help you be seen by other road users in the dark. Wherever you are going, get there faster in the Brooks Launch GTS 9.
