I can honestly say I have never owned a tennis shoe that has fit me right and felt light.
Barricade II - fit well, but leather sides tore and felt very heavy
Nike Breathe Cage 2 - narrow, but were very light and were noticeably easier to play in then barricades.
Nike CB 1.3 - narrow, had to go a size bigger so a little long, excellent shoe..not as light as the breathe cage 2 though.
My ultimate shoe would fit like a barricade and play like a BC2. I wonder if that exists.
