Materials and Components
The term ‘Nappa’ typically refers to a high grade, soft, full-grain leather, but our Vegan Nappa is made from 100% recycled fibers. While standard vegan leathers are made using virgin plastics and harmful chemical processes, our Vegan Nappa is made without any virgin plastics and using a water-based process. Contrary to its name, this water-based process still uses 95% less water than the standard chemical process. Overall energy consumption is also reduced in this process by roughly 55%.
Vegetable Tanned Leather
One of the oldest and most intricate processes for treating leather, vegetable tanning uses organic substances derived from tree bark and plants to prepare the leather to be dyed and used commercially. By using a plant-based process, the leather remains fully biodegradable. The properties of leather make for an extremely long-lasting product that often improves with age. Vegetable tanned leathers are known for their earthy hues and can darken or patina over time.
Our Italian sole factory makes their standard rubber soles by cutting multiple pieces from large sheets of rubber. This creates a large amount of "off-cut" waste, resulting from the irregular shape of each sole. This waste is then melted down and reused to create the regenerated rubber soles you see here. Rubber soles also allow for excellent traction and have natural non-slip properties.
Linings aren't always seen as the most exciting component of the shoe, but they are one of the most important! As the first point of contact with the skin, the material must be breathable, able to wick away moisture, and should be soft to the touch. While leather naturally is a great candidate for the properties needed for linings, the trick for finding a non-virgin plastic vegan option proved difficult until we sourced this groundbreaking material. Made from natural, renewable resources, polyols, or plant-based molecules, are taken from corn, grain, and seeds to comprise a non-petroleum and performance based leather alternative.
Made from 100% recycled and 100% recyclable untreated paper, our fixtures are just as sustainably minded as the rest of our products. We often get asked about these honeycomb structured beauties, and we are constantly moving them around as they are stackable and modular!
