Flex

Lacing System

- TX3 BOA® Lace – Flexible, low-friction textile lace ensures smooth adjustment and lasting reliability.
Liner
- Life Liner – Lightweight, durable liner that balances responsive support with all-day comfort.
- Tuff Cuff Lite – Enhances heel hold and lateral support while allowing natural flex for comfort.
- DRYRIDE Heat Cycle™ Lining – Wicks moisture and reflects body heat inward for all-day warmth.
Outsole
- EST®-Optimized Outsole – Reduces the overall footprint for improved boardfeel and natural stance alignment.
- AutoCANT Cushioning – Dual-density EVA automatically aligns knees and ankles for comfort and control.
- Shrinkage™ Footprint Reduction – Reduces boot profile by one size to minimize toe drag.

Sizing Advice
- Fit – Burton Ion BOA® boots fit true to size; choose your regular shoe size for a precision, performance-oriented fit.
- Snug at First – Expect a firm, locked-in feel initially; the Life Liner will form to your foot after a few sessions or heat molding.
- Standard Fit – Designed for most foot shapes, with Dual-Zone BOA® providing fine-tuned upper and lower adjustments.
- Do Not Size Up – Sizing up compromises heel hold and the responsive feel these stiff boots are built for.
