"The latest ProStance has been substantially redesigned to provide a more modern look and feel and to incorporate a number of new design features which make ProStance even easier to use than before. • More appealing, modern aesthetic design. • Reengineered to provide a more robust and durable product. • Slightly narrower than the original ProStance to more comfortably fit smaller shoe sizes. • Integral Stabilisation Fins fitted at both ends to minimise rolling. • Integral Stiffening Plate fitted to base of ProStance which maximises ground contact and reduces the curling effect evident with the original ProStance."
