I've been riding more or less happily on Burtons for many years (first Reacts, then Wind), and when they broke down I had to start looking on other brands for obvious reasons.
Sadly my feet aren't compatible at all with any of the Deeluxe range - I don't consider myself to have problems with sizing in general (not on Burtons or any ski boots), but on the Deeluxes I could pull the second buckle to the max without feeling a thing. It doesn't have any adjustments to allow tighter fit either. Was sooo happy to discover that Head is shattering the Deeluxe monopoly, so I got the Stratus Pros and a pair of Cirrus (for sale in the Classifieds btw), and love them! All the benefits are covered nicely in the reviews, so I don't have to rave about them.
