The Burton Ion raises the bar yet again. A top-of-the-line full heat moldable liner, that has Ultralon Performance Foam, keeps your feet warm and wicks moisture away. This stiff boot has the Speedzone Lacing system and works with two seperate laces. One for the lower and one for the upper boot. This way you can dial your boot the way your feet like it. The Boa Snugger Strap will give some extra heel hold and the carbon in the heel will give extra stiffness and respons to the boot. You can tuck your pants away in the cuff on the back, this allows you an easy step-on. Micro-adjustable zonal fit and liner tech that keeps feet warmer and drier – all with the legendary responsive feel that put the Ion on the map.
