Brooks Adrenaline GTS 20 Size 11.5 D (standard width) Used No original box This is a used pair of Brooks Adrenaline GTS 20 in used condition. See pictures for condition. I did a fair amount of walking and some running in them. They still feel great, they've just got a little tread wear and some dirt and scuffs from regular wear. Feel free to ask questions or make an offer!
