Since their inception, the NMDs from adidas have been insanely popular, with some colorways fetching upwards of $1,000 on the secondary market. Their latest version, the “Pitch Black” NMD_R1 PK, will, without question, be the most valuable yet—and you can’t even buy them. Most of the pairs are being given to friends, family, and influencers, but there is a chance for you to snag one of 100 pairs being given away. As announced on their Twitter account, adidas will be running a competition on Snapchat for their followers to win a pair. Beginning Saturday, they’ll reveal clues on their Snap Story that will ultimately reveal a phone number to text. Figure out the number, text, and hope you’re one of the lucky few who are selected for a pair of the slickest NMDs yet. Then keep them or sell them for crazy money.
