Not that I know of. But do you really need shoes when you're on the mat? I just wear a pair of generic running shoes whenever I'm doing cardio or lifting and I go barefoot when I'm on the mat or in the ring or whatever.
"I don't want them to like me, because when I'm in the ring, punches fly to the face. It is not a tenderness time. I am not falling in love. And he knows that when the fight starts I am kicking faces."
