Although "knit" has become an important part of the sneaker business, the Concepts x Converse Pro Leather Hi "Aran Sweater" slid under the radar as it released in the spring of 2014. While the name "Pro Leather" might suggest a leather shoe, that's not the case with this Concepts collaboration. The Converse Pro Leather originally released in 1976 as a basketball shoe and was worn by legendary hooper and hall of famer, Julius "Dr. J" Erving, among other NBA players. Nearly 20 years after its initial release, Concepts opted to flip the script on the Pro Leather and give the upper a knitted wool makeover. The "Aran Sweater" comes from Ireland and is traditionally an off white color similar to sheep's wool and features unique and intricate cable patterns across the chest. With that in mind, Concepts gave the Pro Leather a uniquely designed wool upper with equally detailed cable patterns. The Converse Chevron logo gives this design its only color pop with a combination of green and orange on the side panel. Of course, a fully wool upper wouldn't hold its structure so the heel is done in leather with the Concepts logo embossed into the heel panel. With Concepts' Boston roots and Irish ties, the pairing with Converse, who keeps corporate offices in Beantown, makes the Concepts x Converse Pro Leather Hi "Aran Sweater" one of the most appropriate of collaborations.
