The Asadachi III binding from Union. Miles of hyphenated "tech" [love this stuff -ed]; Stage II Base—Dupont™ Zytel® ST, Injected EVA Bushings, Extruded Anodized Aluminum Heelcups, Quick-Adjust Forward Lean, 3D Multi-Layer Strap Core, Tool-Free Size Adjustment, Magnesium Buckles. No idea how it rides but they had me at wood grain finish.
But what is Dupont™ Zytel® I hear you ask?? A nylon resin. And if you want to geek out on the full DDC produced 2010 Union catalog you can peep it here.
