The Brooks Men's Launch 6 are built to be springy & fast, with zero distractions. Designed for quick transitions to get the jump on other runners. BioMoGo DNA midsole cushioning and rebounding rubber create a springy feel underfoot. The Midfoot Transition Zone is shaped to go from heel to toe quickly. The one-piece mesh upper and internal bootie are so light and breezy, they feel like they're not even there.
