The Brooks Glycerin Max running shoes offer an optimized blend of airy softness and electrifying responsiveness with its dual nitrogen-infused cushioning system. The engineered mesh upper provides breathability and a roomy toe box for natural toe splay, enhancing comfort and stability. A plush tongue and padded heel collar, combined with a traditional lacing system, ensure a secure and comfortable fit. The high-stack DNA Tuned midsole delivers bouncy, resilient cushioning for impact protection and comfort, while the GlideRoll Rocker geometry promotes seamless heel-to-toe transitions. A durable rubber outsole provides long-lasting grip and traction on road surfaces. Key specifications include a 6mm drop and a weight of 297.7g. The DNA Tuned midsole utilizes dual-sized cell technology, with larger cells in the heel for soft landings and smaller cells in the forefoot for enhanced toe-offs, all seamlessly integrated for a unified performance. This maximum soft cushioning helps to lessen impact on joints and absorb shock, reducing the risk of injury or discomfort. The sculpted bevel and toe spring of the GlideRoll Rocker further contribute to effortless transitions and improved energy return, allowing you to run further and faster with less effort. The outsole features a unified rubber piece at the front for excellent toe-off traction, with shaved-off sections to reduce weight for faster strides, all designed for long-lasting wear.
