Great used condition Brooks. Minimal wear as they did not fit me. Good for those looking for max cushion and neutral shoes. Details About Women's Brooks Glycerin 20 Women's Brooks® Glycerin 20 :: Super-soft comfort for miles upon miles! Your Women's Brooks Glycerin 20 running shoe has a reimagined cushioning system and sole, offering you the smoothest ride yet. Thanks to the lightweight, Nitrogen-infused DNA LOFT v3 foam, this shoe is more durable, responsive, and comfy than before. To add even more smoothness to each step (because why not?!), a wider platform was designed for the midsole and outsole of your Glycerin GTS 20 providing balanced transitions from heel to toe.
