After launching our Grass Sole style eight years ago, we introduced our Cork Runner sole for Autumn Winter 2018. We challenged ourselves to design a sustainable alternative to the commonly used synthetic EVA (Ethylene Vinyl Acetate) sneaker midsole. After some in-depth prototyping, we successfully constructed our Cork Runner sole from Natural Latex and Portuguese Cork, local to where these shoe styles are carefully crafted. The Cork Runner sole is biodegradable, renewable and is naturally springy so can absorb huge amounts of energy.
