Our Flyweight Finproject XL cleated soles weigh in at just 350grams, but like their namesake they are as tough as old boots. We've created a real depth of colour on the calf leather upper by meticulously applying layer after layer of dye by hand, with darker accents along the seams for an impeccable antiqued look. Fully leather lined and Goodyear welted, finished with a natural leather rand and herringbone cotton back pull tab.
