British online boutique, oki-ni, reached out to fellow compatriot, Dr. Martens, to realize this collaboration footwear. Made completely in Dr. Martens' Cobb's Lane factory in UK, the mid-cut Monkey Boot employs two contrasting leather materials on its uppers. Smooth leather is allocated on the toe, tongue and heel, offset by textured hair-on leather on the side panels. Its iconic PVC "Bouncing Soles" are coordinated in matching colors as the uppers, and securely stitched onto the boots using Goodyear welting method. A choice of Oxblood and Navy versions are available exclusively from oki-ni online store.
