The Synapse JP Wide Boots feature Full Custom Fit foam is heat moldable, multi-density foam throughout the entire liner, and a Mystic Footbed Level 3, the only antimicrobial footbed in snowboarding that increases blood circulation, prevents fatigue and embodies natural healing from the bottom of your feet to the top of your head.

The Salomon Synapse JP Wide Snowboard Boots feature a Liner Balance level of 4; Salomon’s Liner Balance features 4 levels of construction based on the same design philosophy that displaces liner lace pressure from the top of your foot, around the key holding areas of the arch and above the heel while tightening the liner lace to wrap the ankle both firmly and comfortably around, rather than on top, of the foot. Powerlace Pro, in the meantime, gives you fine-tuned tightening at unmatched speeds.

The ultralight Spring outsole is soft where your foot needs to flex and stiffer on the sides for stability and balance. Dual density EVA with thin rubber side stabilizers deliver dampening and transmission on the stiffest hits for so you can go bigger and better.
