It appears that the deal was made before the injury break.

I'm glad i stocked up on the B7/ Novak pro's. IMO, one of the best (if not the ultimate) hard court shoes ever made and excellent on har tru as well. Speaking for myself, simply amazing traction, comfort and stability (except when it's really humid) once they are broken in. Plus, they look amazing. Ah well, all good things come to an end.
