The Brooks Men's Glycerin 22 is a plush neutral running shoe with a nitrogen-infused midsole that delivers soft landings and smooth transitions mile after mile. For runners who want built-in support, the Glycerin GTS 22 adds GuideRails® stability technology to help guide your stride and reduce excess motion, making it ideal for those who benefit from extra support. Both models pair ample cushioning with a flexible, comfortable upper for everyday training, long runs, or casual wear.
