The EST system partially consists of the channel-mounted ShredBED 2.0, which replaces the baseplate of traditional bindings. The ShredBED 2.0, a cushioned, removable platform, helps to absorb impact by spreading it throughout the boot. Thanks to the simple channel-mounted design of the EST system, you can adjust stance angles by the simple pull of a cord, and have more angle options than traditional three-angle bindings. The binding itself (excluding the buckles, cushioning and straps) is all made of the same material, bomb-proof polycarbonate, which provides a laid-back control. The use of a single material for the entire binding creates a consistent feel and response, which helps you to adapt to new territory. The microFLAD system on the hi-backs of the Custom EST allows you to easily micro-adjust, so that you can keep your feet at a dominant forward lean angle. The microFLAD system offers twice the options of Burton's traditional FLAD (Forward Lean ADjustment) system. This binding is a step up from the lower cost Custom Binding in that it has the EST system and the Removable ShredBED 2.0 Cushioning system (which has a stance indicator window, and offers more adjustment options than traditional cushioning systems). There are color and size options available for the Burton Custom EST snowboard binding.
