CLARKS CUSHION PLUS - bespoke footbed engineering provides targeted underfoot cushioning with maximum shock absorption and support to make walking effortless. Three densities of Ortholite foam, carefully placed across the footbed and concealed inside, reduce the strain on the ball of the foot and allow it to sit in its natural position. CLARKS CUSHION SOFT - A concealed foam inlay, made from leading open-cell Ortholite technology, ensures exceptional first touch feel, helps impact absorption with every step and because it doesn’t flatten under pressure or with wear, it provides lasting comfort.
