When you’re running, you don’t want to think about whether you have enough cushion or whether your foot has the proper support. The Brooks Glycerin GTS 21 frees up your mind with ample support, max cushioning, and easy transitions.
For those unfamiliar with the Glycerin line, the Glycerin GTS 21 is Brooks' support-focused version of this shoe, designed to provide stabilization for runners with flat feet or pronation issues.
If you don't have flat feet and you don't overpronate, we'd recommend investigating at the Brooks Glycerin 21, the neutral version of the shoe with reduced weight due to the lack of the support-adding GuideRails.
