Great condition. Nice patina from occasional wear. Lots of life left in these. Vibram sole. The zipper sides allow for a narrower boot shaft, minimizing heel slip. The limited edition John Addison Engineer is a classic pattern named after the brand’s founder. Featuring handmade Goodyear Welt construction and a Vibram sole plate with a padded leather footbed for added traction and a high-quality, comfortable fit. Crafted with waxed brown leathers from Chicago’s Horween tannery, tuck trousers into these boots for a smart-casual look.
