System APX Snowboard Boots : The new and improved APX boot is designed to maximize comfort and performance! An all new forgiving and playful flex pattern allows for a more natural feeling when riding, hiking or even walking in the parking lot. The APX is reinforced in nearly every area from the dense and reactive rubber of the sole to metal loop lacing and double stitching. Even with the added durability the reduced profile of the APX allows it to be one of the lightest boots on the market! Improved Thermofit heat moldable liners create a customizable fit, while an articulating cuff allows for a smooth flex. An added heel locking lace loop means your feet will stay firmly in place, eliminating the slop of many other boots. Finally the System APX continues to use space age waterproofing to keep your feet dry and warm on even the coldest and most wet of days. But if that isn't enough the APX comes with a 3 year guarantee against manufacturer defects, so you will be sure to have a boot that lasts for season after season.
