J/SLIDES black slip ons GUC - runs big

LOVE these comfy J Slides but they’re really big. I typically wear a 7.5 and thought I’d give these size 8s a try, but they fit more like an 8.5. I had to stuff some ankle socks up at the toe in order to wear them. I only wore them once, but they are a re-posh. Very great condition. I’d keep them but the socks at the toes hurt me. 🤪
