4mm Cork Sheets for Shoe Making

4mm Cork Sheets for Shoe Welting – Sold in Pairs.

Available Sizes: 4" x 12" and 6" x 16".

Add comfort, structure, and durability to your shoemaking projects with our 4mm Cork Sheets for Shoe Welting, available in two versatile sizes—4" x 12" and 6" x 16"—and sold in pairs. These high-quality natural cork sheets are essential components for traditional shoemaking techniques like Goodyear welting and hand-lasted constructions, providing a dependable filler material that enhances both function and feel.

Crafted from fine-grain, high-density natural cork, these sheets are lightweight yet firm enough to maintain the shape and integrity of your footwear. The 4mm thickness offers excellent shock absorption, flexibility, and thermal insulation, making it ideal for filling the cavity between the insole and outsole in welted shoes or boots. Over time, cork conforms subtly to the shape of the wearer’s foot, improving fit and comfort with each step.

The 4" x 12" size is perfect for most standard men’s and women’s shoes, while the larger 6" x 16" sheet offers extra surface area for boot soles, orthotic builds, or custom patterns. Whether you're making bespoke shoes, restoring vintage pairs, or adding a supportive layer to your leather projects, these cork sheets are easy to cut, shape, and glue for seamless integration.

Ideal Applications:

• Filling the midsole cavity in Goodyear welted and hand-lasted shoes.
• Creating arch support, heel lifts, or shock-absorbing insoles.
• Building up orthotic footwear or leather footbeds.

Why Use Cork in Shoemaking?
Cork has been a trusted shoemaking material for centuries thanks to its resilience, light weight, and ability to conform to the shape of the foot over time. It helps cushion every step, insulate against ground temperature, and create a strong yet forgiving core beneath the insole. In traditional Goodyear welted shoes, cork not only fills the cavity but also adds longevity and structure to the footwear. It’s a natural, biodegradable choice for makers who prioritize performance and sustainability.
