Finisterre’s surf gear is proof that functional, sustainable design needn’t be devoid of style, and while Brogue hasn’t been shacked in a while, we can’t help but appreciate the Cornish brand’s increasingly innovative collaborations. Designed in collaboration with VIVOBAREFOOT, Ultra Bloom is a super-light totally breathable waterproof shoe made from algae rescued from waterways around the world. The plant-based fabric is a brilliant alternative to petrochemicals, and every pair will help re-circulate 57 gallons of filtered water back into natural habitats, and prevent the equivalent of 40 balloons full of CO2 being released into the Earth’s atmosphere.  The special Bloom Foam is created by harvesting algal biomass from freshwater sources at high risk of algal bloom.
