Experience the next iteration of infinite energy. Brooks’ most responsive midsole, DNA AMP, does more than cushion. It controls, captures, and returns your energy to help fuel your run. Your energy reserves aren’t unlimited. So our engineers stepped in to create a flexible, arrow-point pattern on the outsole to help you move from heel to toe quickly, without losing energy. Comfort goes stealth mode inside the sleek, adaptable Fit Knit upper. Hidden features include a heel wrap and an ultra-soft heel tab to shield your Achilles from irritation.
