Designed with a new engineered double jacquard knit upper, the Brooks Glycerin 22 offer a flexible and accommodating fit while ensuring your foot stays secure.   The broad platform stabilizes your foot while the tuned heel and forefoot promotes smooth heel-to-toe transitions. New DNA Tuned, the next generation of nitrogen-infused foam, is created with dual-size cell technology.  Larger cells in the heel provide plush landings, while smaller cells in the forefoot invite responsive toe-offs. Feel limitless in this super-soft men's running shoe.
