Has anyone ever contemplated trying out a pair of EVO Terra Plana shoes for playing tennis? Is it possible that the lateral support afforded by specific tennis shoes outweighs the design benefit of this kind of EVO shoe? Here's a blurb of the inventor: "Vivo Barefoot were originally created by Tim Brennan, a professional tennis player and coach with the double luck of having an Alexander Technique teacher, Richard Brennan, for a father, and a massage therapist, Gloria Bianco, for a mother. When Brennan junior became injured, his parents advised him to learn to play in bare feet. To protect his feet from outdoor tennis courts Brennan shaved slivers from the bottom of his trainers until the soles were ultra-thin. His injury cleared up and he used his experience to design a new pair of shoes. None of the major shoe manufacturers would take his design, so he turned to his friend, Galahad Clark, who had set up his own ethical shoe company, Terra Plana".
