Specifically built with tennis in mind, the Gel Sensation has apparently been designed to perform 'under multi-directional stresses'. Which, in English, means sprinting off in all directions. Other features include rearfoot gel for absorbing shocks; an anti-gravel tongue to protect your tootsies from flying grit; and RhynoSkin forefront reinforcement to minimise wear due to toe drag (Asics assures us no large horny mammals were harmed while making the shoes).
You can snap up a pair of the Gel Sensation for £80. See MyAsics.co.uk
