Unleash your best self every day with the Brooks Glycerin 22, the ultimate choice for comfort on every run. Experience the ultimate performance of the Glycerin 22 every day. Midsole This model features the new DNA Tuned foam, Brooks' next generation nitrogen-infused foam. The dual-size cell technology ensures a soft landing with larger cells in the heel, while smaller cells in the forefoot provide a responsive push-off. Upper The shoe is highly breathable thanks to the jacquard mesh upper. This material features textured yarns that allow sweat to escape and keep feet cool. As the mesh follows every step of the foot, it provides comfort and support. The pleated tongue of this shoe is attached to the upper on both sides, so that dirt cannot enter the shoe and the tongue remains centered. The Glycerin 22 has an external lacing system that ensures that the laces cannot touch the foot to prevent irritation. Outsole The shoe features a RoadTack outsole, made from a mix of rubber and recycled silica. In addition, this outsole technology from Brooks is durable and resilient to compression, making them extra long-lasting.
