UNION Flite PRO 2020 model LARGE size only $200 so cheap

medium is US8 to US10.5 and large is US11 to US12 possibly US13 depending on boot. 

perfect for an all mountain shred - like all PRO models - its SUPER Light

probably the best binding for a beginner wanting a softer flex, 

BUCKLES

Injected Aluminum Buckles – Fast in, and fast out. Union aluminum is second-to-none.

HIGHBACK

Fusion Highbacks – Lateral tweakability in any temperature supplies a seamless connection with your boot.
