Stephen M.wrote a review of Burton Ambush Snowboard Boot - Men's on May 3, 2013
I'm not sure I would have called the lacing system 'Speed Zone', it takes me just as long to wind the strings up after as it does to tie a normal boot. I will say however, that it doesn't bother me, because the adjustability is fantastic! I like to have my lower boot loose so my feet have some room, but my upper boot tight so I stay secure, and this is the best I've had in a boot. Also, the lacing system is extremely easy to adjust on the go too (maybe thats where the 'Speed Zone' name comes from). Instead of having to re-lace the entire boot, you can just tweak whichever spot needs loosening or tightening.
