Focusing on feeling good, thirtytwo's Shifty Snowboard Boot boasts a Comfort liner that's lined with micro-fleece for a cozy-warm feel without irritation. This liner is comprised of Intuition foam for an adaptive, heat-moldable fit that wraps our feet in heavenly comfort. The Shifty is finished with an internal lacing system that tightens over the liner to eliminate heel lift, as well as an impact-absorbing STI Evolution Foam outsole for plentiful grip across icy parking lots and sidewalks.
