Frye and Co. Mens Oliver Stacked Heel Monk Strap Chukka Boot 。Origin: Made in Chippewa Falls, Wisconsin, USA (Authentic Union Made) The industrial factory sizing and original Boot & Shoe Workers\' Union stamps are as crisp, stark-white, and perfectly legible today as they were the day they were stamped over 50 years ago. They feature a distinct soft square toe, a secure single monk strap with an aged brass buckle, and iconic vintage O\'Sullivan rubber safety heels (historically known as \"America\'s No. 1 Heel\"). Premium Leather Uppers: Thick, supple, oil-tanned brown leather that has developed a beautiful, authentic vintage patina. Genuine Leather Quarter Linings: The high-quality interior leather perfectly preserved the factory markings (Style 897k). Built to Last: Solid Goodyear-style construction meant to be serviced, not thrown away. CONDITION: Uppers: Excellent vintage condition. The leather is robust, structurally sound, and free of deep cracks, dry rot, or major scuffs. Light, natural creasing and minor toe character marks only add to their vintage appeal. Interior: Exceptionally clean, pristine ink stamps, and very minimal wear. Soles: Features vintage protective rubber half-soles and O\'Sullivan rubber heels added by a cobbler over the original leather base. One sole shows classic vintage adhesive residue/slight edge separation from an old repair (visible in photos), but they remain fully intact and solid. Add a rare piece of union-made Wisconsin footwear.
