Prepare for effortless-feeling everyday runs. The ultimate ride sensation with soft CloudTec® Phase cushioning. The ultimate ride 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. More durable tread 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. Boosted breathability The re-engineered upper now features a more breathable mesh construction.
