WTT stands for "Want To Trade" and is used by sneaker enthusiasts to indicate their desire to exchange a specific sneaker they own for another sneaker they are interested in. For example, if someone owns a pair of YEEZY BOOST 350 v2 Zebra and they want to trade it for another pair of sneakers, they would use the WTT abbreviation in a post or message to indicate their willingness to make a trade. Sneaker trading is a common practice among sneakerheads, and WTT is often used in online sneaker communities and forums to facilitate trades.
