Using Finite Element Analysis (FEA) to optimise the midsole's geometry we formulated the ultimate ride, in a light and durable shoe with buttery-smooth transitions underfoot. Using FEA analysis, we crafted a more durable outsole with thicker padding and smaller cavities in the tread. Built to last, this updated geometry supports an even smoother ride. The re-engineered upper now features a more breathable mesh construction. Breathable mesh upper made from recycled polyester. Embroidered overlays – also made with recycled yarn – provide support and structure around the foot.
