Make comfort a priority this season with Oliver, a smart, comfortable leather trainer. Helping you to go further for longer with energy-returning Cushion+ technology, cleverly absorbing the impact of each stride and returning energy to the next. Also including a dual fit insole, Oliver has a removable foam insole underneath its top insole, which can be removed to offer a roomier fit. The uppers are made of leather, with a leather/textile lining and a PU sole. They fasten with laces and have a standard fitting.
