Whether you're training for a marathon or just enjoying a casual run, the Brooks Glycerin 22 is the ideal all-round running shoe. 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 open structure of the jacquard mesh upper increases the breathability of the shoe, while the textured yarns ensure that sweat can escape and the shoe remains dry on the inside. The elasticity of the mesh increases the level of comfort and support as the mesh follows every movement of the foot. To keep the tongue centered and prevent dirt from entering the shoe, a pleated tongue is connected to both sides of the upper. The lacing system of the Glycerin 22 is designed in such a way that the laces do not 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.
