Don't sleep on Facebook: There's more to it than dumping vacation photos into albums and letting everyone know your every emotion. Facebook is a great way to find groups for buying and selling sneakers. Instead of posting a for-sale ad on your own timeline for all your aunts, uncles, and cousins to see, these groups give you a place to have you kicks seen by sneakerheads just like you.

Many buying and selling groups are localized for specific regions like New York City or are for specific types of sneakers like Yeezys. You'll reach a specified audience and will be able to communicate with the exact person who's interested in whatever's being sold. It will also allow you to vet who's making a purchase.
