Reebok DMX Upset vs. K-Swiss Defier

[Revman]

I'm considering trying the DMX after a couple of years of wearing Defiers. I would very much appreciate opinions regarding fit, stability, durability, etc from anyone who has worn both. I'm especially concerned about fit. Ideally in the case of the Defiers I would wear something between 10-1/2 and 11, so must decide between those sizes if I buy the DMX.
