A couple of days ago we gave you the first look at the brand new Nike Free Socfly. For us an instant summer hit, as it combines a sock upper construction, strap and lightweight Free 3.0 sole. Today we take a look at the more limited Nike Free Socfly SD, which comes in a black/gradient version and a tonal all university red version. If you are looking for a minimalist sneaker that pops, this might be up your alley. You can pick them up already from Undefeated Japan.
