ACG Air Skarn sneakers The Nike ACG Air Skarn is a revived version of the 1997 silhouette that was released under Nike's famous All Condition Gear line. Tough and ready for any type of weather, the bulky hiking shoe is created with layers of suede, mesh, and rope-style piping wrapping around the heel just under the lacing system. ACG branding flanks the lateral side of the heel and a unique inset is positioned in the middle of the midsole. This colorway pairs sequoia and vivid purple with army green, citron, and navy blue.
