I sell most of my shoes on Depop. I list on eBay first, then cross list to Poshmark, Depop, and Mercari. Once you learn about shoes they are easy to list and sell. Do your research. I've been doing research on the different item specifics in eBay to help me create a better title and listing. Just like clothing, you need to check the STR. With shoes/boots the item specifics need to be more precise to get the best STR. I just listed 4 pairs of shoes on eBay and then cross listed. They are all preowned and listed between $40 ad $65, with a great STR. I found them at thrift stores I visited yesterday, an hour and a half from my house. I need to expand to get the good stuff.
