Reebok is teaming up with rapper Gucci Mane, who posted several pictures of his new sneaker collection on his Instagram last week. The deal comes just days after Reebok also signed singer Ariana Grande. Josh Luber, CEO of StockX, says Reebok's sneaker deals are typically hit or miss, so only time will tell. Plus, Luber unveils StockX's fundraiser for victims of Hurricane Irma and Harvey. Celebrities such as Karlie Kloss, Lebron James, and Pharrell are donating their sneakers on the site to raise funds for hurricane relief. One of StockX's lead investors, Eminem, will match the amount raised.
