This classic derby shoe showcases Carol Christian Poell's refined approach to traditional shoemaking, featuring authentic Goodyear welt construction with full leather lining that provides both durability and the sophisticated aesthetic language characteristic of the brand's formal footwear offerings. Crafted from ROOMS-PTC, a premium kangaroo leather measuring 0.7-0.9mm thickness and treated with the Object-Dyed Process in color 29 blue, the leather is dyed as a complete assembled shoe to create unique surface variations and the distinctive patina that develops through wear.
