The SFX EVO is the perfect shoe for anyone, from amateurs to advanced players, who wants absolute comfort on any surface. The larger volume in the forefoot and the comfortable design promise an unrivalled first fit experience. This is the perfect shoe if you have a "strong" and rather wide foot. In terms of design, we've retained the flexibility and support that you expect from a tennis shoe, in a unique, streamlined look for wearing when playing all your games.
