Answer:
At events like Sneaker Con, which takes place in cities around the
world, thousands of enthusiasts get together to buy, sell, and swap sneakers. Attendees can have rare or valuable
purchases authenticated by experts.
The business of buying and selling sneakers is booming, fueled in part by the Internet and social media. Apps help
shoppers locate hard-to-find shoes, whether they're up-and-coming releases, current models that are sold out in stores,
or old classics.
