S.B. Foot Slate Muleskinner is a grey-toned variant of S.B. Foot Muleskinner roughout leather, produced by S.B. Foot Tanning Company in Red Wing, Minnesota. The slate colorway presents a neutral grey tone that provides visual versatility while maintaining the rugged aesthetic and technical characteristics of the Muleskinner leather line. Red Wing Heritage introduced slate muleskinner in their product line around 2021, utilizing the leather in the Classic Moc style 8863 and the Iron Ranger style 8087.
The slate color represents a departure from the warmer earth tones traditionally associated with Muleskinner leather, offering a cool-toned alternative that appeals to customers seeking a more subdued color palette. The grey coloration combines with Muleskinner's characteristic roughout construction to create a leather particularly suited to both heritage footwear and contemporary casual wear. The neutral tone allows the slate variant to integrate with a wider range of clothing styles than more saturated leather colors.
Slate Muleskinner presents a grey coloration that ranges from light to medium grey intensity depending on the specific hide section and lighting conditions. The color designation references slate stone, which exhibits similar grey tones in natural building materials. This neutral grey appearance distinguishes slate from the brown and tan tones of Hawthorne Muleskinner or the olive green of other Muleskinner variants, providing a distinct visual identity within the product line.
The grey tone results from dye application to the buffed flesh side of the hide, with the roughout texture influencing how the color appears on the leather surface. The napped texture created by buffing the flesh side diffuses light differently than smooth leather, giving the grey color a softer, more matte appearance rather than a flat uniform tone. This textural quality adds visual depth to the slate color even on new, unworn leather.
The neutral quality of the slate tone comes from the grey pigment selection that creates a desaturated appearance without warm or cool color bias. This balanced grey makes slate Muleskinner versatile for pairing with both warm and cool clothing colors, avoiding the color coordination constraints that more saturated leather colors impose. The grey tone also shows less visible contrast with dirt and wear marks than lighter natural leathers, contributing to the leather's ability to develop an attractive patina.
Red Wing Heritage established slate Muleskinner as a leather option for the Classic Moc style 8863, introducing the grey roughout variant alongside traditional Muleskinner colors. The boot features the characteristic moc toe construction with white Traction Tred wedge sole and Goodyear welt construction that define the Classic Moc line. The slate Muleskinner upper provides the same water-resistant properties and durability as other Muleskinner variants while offering the distinct visual appeal of the grey coloration.
The Iron Ranger style 8087 employs slate Muleskinner in a design based on traditional work boots worn in Minnesota's Iron Range mining district. This model features the cap toe construction with cork sole and heel that characterize Iron Ranger boots. The slate Muleskinner leather contributes both the rugged durability expected from work boot heritage and the contemporary aesthetic that appeals to heritage footwear collectors. Red Wing designated the 8087 as a North America exclusive release, limiting availability to the North American market.
Beyond Red Wing Heritage's signature models, the neutral grey tone of slate Muleskinner makes the leather appropriate for custom leather goods where color versatility supports various design applications. The combination of technical roughout construction and subdued coloring works effectively for accessories including bags, wallets, and straps where water resistance proves valuable but bright or saturated colors would conflict with intended use cases. The grey tone particularly suits urban and contemporary designs where neutral colors predominate.
Slate Muleskinner develops character through use, with the roughout surface showing wear patterns that enhance the leather's appearance over time. High-wear areas become burnished and compressed, creating darker sections that contrast with less-worn portions of the leather. This natural darkening occurs as the nap compresses and surface oils migrate to areas experiencing the most friction and flexing. The grey base color provides a neutral background that makes these wear patterns particularly visible and visually interesting.
The grey tone incorporates dirt and staining into the leather's appearance rather than showing it as obvious damage. Slate Muleskinner has the ability to absorb superficial dirt and incorporate it into the developing patina, with the neutral grey color helping to conceal marks that would appear prominent on lighter colored leathers. This characteristic makes slate Muleskinner practical for footwear and goods that will encounter regular environmental exposure without requiring constant cleaning to maintain appearance.
As the leather ages, the slate tone may shift slightly as the grey pigments fade at different rates and the natural hide color beneath becomes more apparent. Some sections may develop warm undertones while others maintain the original cool grey appearance, creating subtle color variation that adds visual interest to well-worn items. The roughout construction supports this aging process without requiring heavy conditioning, allowing natural wear patterns to develop organically while the leather retains its structural integrity.
Slate Muleskinner requires regular brushing using a nubuck or suede brush to remove surface dirt and restore the nap texture. The stiff bristles of a suede brush differ from standard horsehair brushes used on smooth leather, providing the necessary agitation to lift and clean the roughout surface without damaging the nap. The grey color shows less immediate visual change from brushing than lighter colors, though regular maintenance remains important for preserving the leather's appearance and texture.
Deeper cleaning requires nubuck suede cleaner applied with a damp cloth or specialized suede cleaning tool. The grey color tolerates cleaning products better than some lighter leathers, with less risk of discoloration from appropriate cleaning solutions. Products should still be tested on inconspicuous areas before full application to verify compatibility with the slate dye. Using excessive water or aggressive scrubbing risks compressing the nap permanently, so cleaning should use minimal moisture and gentle pressure.
Leather protector products designed for roughout and nubuck leather help maintain the water resistance that Muleskinner construction provides. These treatments should be reapplied periodically based on exposure conditions and visual assessment of the leather's moisture resistance. The slate color generally tolerates waterproofing sprays without significant color change, though some products may slightly darken the grey tone. Regular maintenance preserves both the technical performance and the visual characteristics that define slate Muleskinner's appeal.
