Last month, we revealed to you that Nike would be releasing a Black Pack version of its "Genealogy of Free" collection as the second drop to commemorate the 10th anniversary of Free technology.

While the collection was supposed to begin hitting select Nike Sportswear retailers starting April 26, the release (if any) has been strangely low-key for a commemorative collection. That all changes now, though, as it looks like Madrid's Sivasdescalzo announced that they would be releasing at least one of the sneakers in the collection—the Nike Sock Racer—on May 15.

While no other retailers have made an announcement, this solid date gives us hope that additional NSW stockists will be releasing around the same time. If you're looking to cop these O.G. runners in the special black colorway, circle your calendar for May 15 and keep your eyes open for additional release locations.
