Our Goodyear welted semi brogue Oxford is made from Prime black calf leather. A semi brogue has the classic punch hole detail but with a straight toecap rather than the wingtip of a classic brogue. Inside we’ve included a full calf leather lining with a half leather insock cushioned at the heel. The upper is set on a formal last with a slightly squared toe and Goodyear welted to a sturdy leather sole. The Goodyear welt channels the stitching through a leather welt around the outside of the shoe making a practical construction.
