The Casper Boot is a side-zip boot manufactured by Rolling Dub Trio, a Japanese heritage footwear company based in Tokyo. Made from a single piece of Horween Chromexcel leather, the Casper features seamless construction achieved through a specialized hand clipping process. The boot sits on a custom-made cork crepe outsole with Goodyear Welt construction and incorporates Cat's Paw metal toe guards and heels.
Rolling Dub Trio [INTERNAL_LINK: 68028874903fc39d87748a78] produces the Casper in small batches at their Tokyo facility, "The Boots Factory," located in Asakusa. The boot represents a modern interpretation combining elements of both engineer boots and chelsea boots, designed to accommodate the flatter foot shape typical of East Asian customers while appealing to heritage footwear enthusiasts globally.
The Casper Boot's most distinctive feature is its construction from a single piece of USA Horween Chromexcel leather, creating a seamless upper without traditional stitching or panels. This wholecut construction requires the highest degree of craftsmanship, accomplished through a specialized process called "clipping" performed entirely by hand. The technique shapes the flat leather into the boot's three-dimensional form while maintaining the seamless aesthetic.
The boot features Goodyear Welt construction, connecting the upper to a custom-made cork crepe outsole that provides all-day comfort. Cat's Paw metal toe guards and heels enhance durability, while the cork crepe material offers a distinctive aesthetic compared to traditional rubber outsoles. The heavy-duty brass side zipper includes a subtle Rolling Dub Trio stamp and is paired with a fully leather-lined interior.
Built on Rolling Dub Trio's CBT02 Last in D width, the Casper maintains a slim ankle boot shaft that complements fitted denim. The waves of leather creasing that develop from the instep to fore-ankle area represent unique aging characteristics resulting from the one-piece upper construction.
The Casper Boot utilizes USA Horween Chromexcel leather, a combination-tanned leather known for its durability and aging characteristics. Rolling Dub Trio [INTERNAL_LINK: 68028874903fc39d87748a78] sources original leathers from the United States, Italy, and Japan, with hand finishing completed in Japan at their Tokyo facility.
Cat's Paw hardware, including both the metal toe guard and heel components, represents a connection to heritage American footwear. These components were originally produced by the Cat's Paw Rubber Company before its absorption by Vibram in the 1960s. Rolling Dub Trio uses deadstock Cat's Paw materials as part of their commitment to traditional construction elements.
The brass zipper hardware features heavy-duty construction suitable for regular use, with the Rolling Dub Trio brand stamp subtly integrated into the zipper pull design.
Rolling Dub Trio [INTERNAL_LINK: 68028874903fc39d87748a78] manufactures the Casper Boot in small batches at "The Boots Factory," their production facility located in Asakusa, Tokyo. Asakusa sits within Tokyo's Taitō ward, an area recognized as a center of traditional leather and shoe craftsmanship.
The company employs old world construction methods, including two-row stitchdown and 360 flat welts, building footwear designed to be fully rebuildable and recraftable over time. Each Casper Boot is handmade by founder Katsuya Tokunaga and his team of skilled craftspeople, using small-lot production methods that prioritize quality over quantity.
The hand clipping process used to shape the seamless upper represents a specialized technique requiring significant skill and experience. This process transforms a flat piece of Chromexcel leather into the boot's curved form without creating seams or visible construction lines.
The Casper Boot follows Rolling Dub Trio's sizing system, which runs larger than typical US footwear sizing. Customers should size down 1.5 sizes from their normal size for D width feet, or one full size for wide feet or higher arches. For average volume D-width feet, the recommendation is one full size smaller than Brannock measurement.
The boot design accommodates the typically flatter foot shape common in East Asian populations, with a longer, rounder, and narrower profile compared to most American work boots. The CBT02 Last does not feature the strong arch support characteristic of American boot makers, instead offering a more relaxed fit through the arch area.
The slim ankle boot shaft design makes the Casper particularly suitable for wearing with fitted denim and tailored clothing, distinguishing it from bulkier heritage work boot styles.
The Casper Boot is available in multiple Horween Chromexcel leather colors, including Black, Navy, Natural, and Oil Burgundy variants. Rolling Dub Trio [INTERNAL_LINK: 68028874903fc39d87748a78] also produces the boot in Black Oiled Suede for customers preferring a napped leather finish.
In the United States, the Casper is available exclusively through authorized retailers including Standard & Strange and Butterscotch, with ButterScotch serving as the first US retailer to launch Rolling Dub Trio products in 2018. The boots are also available through URAHARA and other heritage footwear specialists.
Pricing typically ranges from approximately $600 to $800 for new pairs through authorized retailers, reflecting the small-batch production methods and premium materials used in construction.
