It’s strange to think that the Sock Dart is actually a retro release. Originally released in 2004, the Sock Dart was part of the burgeoning Nike Free movement. Today, lightweight knits and seamless, one piece uppers are a familiar part of the sneaker landscape. What makes the Sock Dart special is that it doesn’t look like the ancestor of contemporary footwear; it looks like the latest and greatest thing off the line. If a size is not listed, it is sold out.
