The Hi-Flex EVA bushing system cushions impacts while keeping response sharp. Mounting compatibility is Step On® 4x2 Disk + Washer, 4x2, Step On® Channel Disk and  Channel — check with thinkempire.com to confirm fit with your board's channel, EST, or 4x4 system.

Who it's for

The Astra Step On® suits women who ride the whole mountain and value convenience without compromise. The Step On® system eliminates fumbling with straps at the top of every run, making it ideal for high-mileage days. If you already ride or plan to ride Step On®-compatible boots, this binding delivers the response and adjustability you'd expect from a dedicated performance binding.
