Walnut is a rich brown colorway of Nicks - Seidel Max Support Smooth leather, a 7-8 ounce oil-tanned steer hide produced exclusively for Nicks Handmade Boots by Seidel Tanning Corp. in Milwaukee, Wisconsin. This leather features a smooth finish in warm walnut brown coloration, representing Nicks' stiffest and most supportive work leather option. Max Support Walnut Smooth is designed for wildland firefighters, foresters, loggers, linemen, and workers in demanding environments where maximum foot support and protection are required.
The walnut colorway provides a warm, professional appearance that works excellently in both work and casual applications. The smooth finish delivers a clean, refined aesthetic while maintaining the exceptional structural support characteristic of Max Support leather. The oil-tanning process creates natural water resistance and durability, with the leather developing rich, complex patina over time as the walnut tones deepen and gain character.
Seidel Tanning Corporation produces Max Support Walnut Smooth exclusively for Nicks Handmade Boots using chrome tannage methods followed by oil-tanning. The leather is sourced from cow hides and processed at Seidel's Milwaukee facility, where it is soaked in oil after initial tanning to create a protective coating. The leather contains 10 to 15 percent oil by weight, providing semi-soft and semi-flexible temper while maintaining exceptional stiffness.
The smooth walnut finish is applied during the tanning process, creating a uniform, rich brown appearance with warm undertones. Unlike Seidel's heavily hot-stuffed leathers such as 1964 leather, Max Support Smooth contains less oil infusion, resulting in a firmer and more rigid temper that provides maximum structural support.
Max Support Walnut Smooth has a weight of 7-8 ounces, with each ounce of leather translating to approximately 0.4 millimeters thickness. This makes the leather twice as thick as industry-standard work boots and three times thicker than dress shoes. The substantial thickness provides exceptional support and protection for extreme work conditions.
The walnut coloration maintains consistency throughout the leather thickness. The smooth finish provides a clean, uniform surface that is easier to clean and maintain than textured leather finishes. The oil-tanned construction creates a protective coating that increases water resistance and durability.
Max Support Walnut Smooth is Nicks' most heavy-duty leather option, specifically engineered for the most demanding work environments. The leather's exceptional stiffness provides superior foot and ankle support, reducing fatigue during long work shifts. The thick construction offers protection against abrasions, punctures, and impacts common in industrial and outdoor work settings.
The oil-tanned finish provides natural water resistance, helping boots maintain integrity in wet conditions. The smooth walnut surface offers a refined, professional appearance suitable for work environments while providing versatility for casual wear. The leather maintains its structural integrity under extreme heat and rugged terrain, making it particularly suitable for wildland firefighting applications.
Walnut smooth leather develops exceptional patina through use, with the smooth surface gaining rich depth and character through natural wear patterns. The oil-tanned construction allows the leather to age gracefully, with high-wear areas developing a deeper burnish and richer color. The walnut coloration deepens over time, creating beautiful variations in tone and showing complex color evolution.
The full-grain construction ensures that the leather maintains its integrity throughout its lifespan, with aging adding character without compromising structural performance. Natural oils and environmental elements are absorbed into the leather, enriching the walnut color and creating unique wear patterns specific to each boot's use history. The warm brown tones with natural undertones provide an excellent canvas for patina development, showing dramatic changes while maintaining refined, sophisticated character.
Max Support Walnut Smooth requires extended break-in time as Nicks' stiffest and most supportive leather option. The firm temper and substantial thickness ensure that boots maintain their structure and support characteristics throughout the break-in period. The leather is designed for maximum support rather than immediate comfort, making it ideal for workers who prioritize foot and ankle stability in demanding environments.
Despite the extended break-in requirement, the leather conforms to foot shape over time while maintaining arch support and ankle stability. The oil-tanning process provides some flexibility compared to purely chrome-tanned leather, allowing the material to gradually adapt to the wearer's foot without sacrificing support.
Max Support Walnut Smooth is relatively low-maintenance leather. Natural oils from feet provide sufficient moisturization for the interior side. For cleaning, the smooth walnut surface can be wiped with a damp cloth to remove dirt and debris. The medium brown color provides good tolerance for dirt accumulation between cleanings.
If the leather becomes wet, it should air dry overnight without exposure to direct heat, as heat can cause shrinkage. For conditioning and protection, boot oil can be applied for conditioning, and leather grease for maintaining water resistance. The smooth finish accepts conditioning products readily, making maintenance straightforward compared to textured leather finishes. Conditioning will darken and enrich the walnut color, enhancing the leather's depth and accelerating patina development.
Max Support Walnut Smooth is utilized by Nicks Handmade Boots for professional work boots where maximum support, durability, and a refined walnut appearance are required. The walnut smooth finish provides a professional aesthetic that works well in demanding work environments while offering versatility for casual applications. The warm brown tone provides a sophisticated alternative to both tan and chocolate colorways.
The leather's combination of exceptional stiffness, water resistance, and heat resistance makes it appropriate for the most demanding work environments. Nicks offers Max Support Walnut Smooth with no price upcharge, positioning it as an economical yet highly durable option compared to premium leather alternatives.
