robhigareda:as a side note, just cause they use them for taping doesn't mean they are normal workout shoes ;) The Air 90 I believe are more fitted to a street shoe rather than a true workout shoe.
They have used them quite a bit in the filming's though! I ordered mine as something a bit different to Shox (of which I have 4 pairs!) and NIKE Free's. I must admit, see D&R in photos of doing workshops around the world, they nearly always wear Shox these days. 
I'll let you know how my Air 90's fair when they turn up!
