The Brooks Glycerin Max Running Shoes are designed to optimize airy softness and electrifying responsiveness. They feature two types of nitrogen-infused cushioning, seamlessly tuned into one midsole for a redefined running experience. The engineered mesh upper provides a lightweight, breathable, and comfortable fit with a roomy toe box for natural toe splay. A plush tongue and heel collar enhance comfort, and a traditional lacing system ensures a secure fit. The high stack DNA Tuned Midsole offers bouncy, resilient, and cushioning comfort underfoot, while the GlideRoll Rocker Geometry provides seamless heel-to-toe transitions. The durable rubber outsole ensures long-lasting grip and traction for confident strides. The shoes have a 6mm drop and weigh 297.7g. The engineered mesh upper is soft, breathable, and features micro-perforations to manage heat and moisture. 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 better toe-offs, all seamlessly joined for unified performance. This high stack of cushioning helps protect joints from impact and absorbs shock. The sculpted midsole bevel enhances energy return, allowing you to go further, faster, using less energy. The durable rubber outsole provides excellent grip on road surfaces and is designed to resist wear and tear for long-lasting use.
