Update: only the 1 pair of regular (non-GTS) left. Other 2 sold. I have 1 pair of brooks glycerin 21 shoes in size 8.5. wide width. Brand new. The pair is regular (non GTS) and I wore them for 5 minutes in the house before realizing they were not for me. I had an ankle injury when I bought them so I couldn’t try them on at the time. My recovery was longer than expected so I went past the return window. Originally purchased on sale for $130 each (regularly $160). See screenshot of receipt for more details.
