The Burton Photon BOA boots are designed for riders who want power, precision, and comfort with the convenience of a BOA system. They use a Dual Zone BOA Fit System with Coiler and Lockdown technology, which allows you to separately adjust the upper and lower zones of the boot while pulling the heel snug for a secure hold. The boots feature an Imprint 3 heat moldable liner with moisture wicking and heat reflective technology to keep feet warm, dry, and comfortable. The liner includes a Focus Cuff that wraps around the ankle for improved heel hold and support.
