Blood Core Leather: A collaboration born from patina and passion

Blood Core leather, developed in collaboration with Rose Anvil and Seidel tannery, isn’t just another black hide. It’s a concept that fuses craftsmanship, chemistry and storytelling into a material that reveals its character the more you wear it.

The idea started with a love for patina, the natural transformation that happens as leather ages and records your experiences. Traditional T-core leathers have long been celebrated for their hidden colour beneath the surface, a black top coat that slowly reveals a lighter core over time. Blood Core takes that philosophy and pushes it further, with a vibrant red beneath a heavy black coat, which as the leather flexes, scratches and wears a red begins to emerge.

Achieving this effect wasn’t simple, the challenge was to make the core itself red all the way through, not just tinted at the surface. After several rounds of development samples, the tannery managed to create a leather that was black on top but red through its entire structure - even a deep gouge won’t anything other than a deep red. This means the patina isn’t just visual, it’s structural. Blood Core isn’t a finish that rubs off easily, it takes genuine wear, flexing, scratching, scuffing, to bring the red to life. Each pair becomes a canvas for experience, as we ship each pair full black, then what it becomes depends entirely on you.

One customer perfectly captured this experience: “These shoes are amazing. I absolutely love the fit, the style, and the fact that they will develop a very unique patina that will tell our story. The story of where we will travel together. I can't wait to age with these shoes. My favourite thing about these is how unique they will become to my persona and way of style and living.”

And another saying: “The smugs are just now broken in, the leather has formed around my feet these are amazingly comfortable shoes. I look foward to wearing these now. I will let the red patina come out naturally with my 501s scuffing them up nicely.”
