The Men's Burton Ion Step On Boots feature a Speed Zone® and Boa® Lacing System that keeps you quick on your feet. You no longer have to deal with traditional laces that easily untie or tangle. Just slide your feet in and adjust the lacing system to your desired tightness. • Burton New England Rope Laces have a lifetime warranty and are virtually indestructible. The fiber ropes are comparable to those used by firefighters and other rescue teams to provide incredible strength. • These boots include DRYRIDE Heat Cycle™ Lining for warmth and ventilation. Your body heat stays in while wicking technology gets rid of any unwanted moisture. An added Tuff Cuff provides extra ankle stability and support with full freedom from toe to heel. • 2020 Men's Burton Ion Step On Boots give you a direct connection to your snowboard gear with a Step On® EST® Outsole. Recycled rubber content and sleeping bag reflective foil reflect heat from the bottom of your boots back to your feet for consistent comfort. • The 1:1 Firm Flex PowerUP Tongue grants an accurate fit to your exact shoe size and Shrinkage™ Footprint Reduction Technology makes it easier to walk when you're unlocked from your board. Catching your toes while walking is now a problem of the past.
