Look Deltas.
Why??? Nice wide platform. The earliest to 'grab' the market. The only true C&V roadie cleat; are the others even vintage yet? I don't follow component timelines.
edit: had Look release-able ski bindings before cycling shoe bindings. It just works. The compatibles work well, too - generally.
