Liner
Life Liner:

Ultralon Performance Foam: Offering excellent thermoforming abilities and minimal water absorption.

Dryride Heat Cycle™ lining: Utilizes interwoven thermally activated carbon thread to capture, radiate, and reflect body heat inward to keep feet warmer while also wicking heat-robbing moisture outward for all day comfort.

Tuff Cuff with Velcro® J-Bar Interface and Inner Lace Lock: Increases heel hold and wraps the ankle with medial and lateral support while still flexing freely from toe to heel.

Asym Velcro® Liner Closure.

Level 2 Molded EVA Footbed with ESS Support Shank, Dual-Density Cushioning and AEGIS™ Antimicrobial Coating
Thermo-moldable Liner
Yes
Outsole
EST®: By eliminating the ramp angle of your outsole, EST lowers your center of gravity, improves board feel, and creates a more surf/skate-like feel without sacrificing an ounce of cushioning thanks to ultra-dampening ReBounce and B3 Gel inserts.

Shrinkage™ Footprint Reduction Technology: Reduces the boot’s overall footprint one full size, meaning a men’s size 10 fits like a size 10, but has the footprint of a typical size 9. Shorter, lighter, sleeker—never suffer from toe drag again.
Flex and Response
1:1 Firm Flex Powerup Tongue: Dual density, 3D molded tongue construction. Available in one of three flex options based on the boot.
Comfort
Total Comfort Construction: Total Comfort’s industry-exclusive construction eliminates the break-in period for a fit that feels just as good from day 1 to 100.

AutoCANT Cushioning: Dual-density EVA allows your foot to settle into a more natural and relaxed position, resulting in improved comfort, reduced fatigue, and smoother, more direct board control.

Outer Pressure Relief Panel: Ultra-soft cushioning is fused to the area where the ankle strap rests on the boot for even pressure distribution when bindings are cranked tight.
