Sperry Chelsea boots - “8.5” but really an 8

Make an offer; I won’t be offended. I missed the return window on these. They’re Sperry brown leather boots, slip-on with elastic on the sides. Never worn except stomping around my apartment trying to decide if I could stand it long enough to stretch them out (answer: no). I missed the return window because I trusted that the sizing would be the same as all other Sperry’s and most other brands: usually comfortable right off, maybe a little stretching required. These are labeled 8.5, but even after I scuffed the insides to hell trying to jam my foot in, I realized they were too tight to wear long enough to stretch out.
