Online resale platform eBay is growing its investment in the sneakers market after acquiring Sneaker Con's authentication business. Garry Thaniel, general manager of sneakers at eBay, spoke to Cheddar about why this was an ideal time to take the already established relationship between the companies to vet collectible footwear. "The sneaker market is valued at over $20 billion, and what we've seen at eBay is quarter-over-quarter, double-digit growth," he noted. "When we talk about our partnership with Sneaker Con, we've authenticated over a million and a half sneakers in just over a year."
