The Burton Ion Leather snowboard boot is tailor made for aggressive, powerful riders. The Speed Zone lacing system allows you to independently adjust the fit at the top and bottom of your boot, to ensure that your feet stay put. The Seamless Power Spine backstay stiffens up the boot for high-energy heelside turns. Naturally, the Infinite Ride 4 liner is heat moldable, for a broken-in fit before you even get them out on the hill. The upper is built from genuine Red Wing leather, so it looks super classy, in addition to being hard wearing. Plus, it's got Shrinkage technology, to give you the smallest possible footprint and less toe overhang. Whether you get your kicks in an icy super-pipe, or charging down no-fall chutes, the Ion gives you the response you need to make your move.
