Head Mya 12LX 97mm Brake Binding - Women's: The HEAD MYA 12 LX is the lightest Diagonal release binding available on the market - ever. So, what does Light Diagonal (“LD”) mean anyway? The LD toe allows the boot to release in a full 180˚ spectrum, providing maximum safety during backward-twisting falls. The LD heel allows the boot to release in a broad 150˚ spectrum, reducing the load on knees and ligaments in both backward and forward-twisting falls, thus reducing the risk of injury. The culmination of so much technology results in a lightweight, performance-driven binding with safety capabilities rarely seen in the ski industry today. The bright, energizing cosmetics also perfectly match the beautiful HEAD Mya No. 9 skis, so you know you will be both safe and stylin' on the slopes.
