The last generation of clickers and switch binders had highbacks on the binding instead of in the boot. Part of it was people complaining about the boots not being as comfortable, and part of it was to try to make them more like a standard binder. What they really should have been focusing on was the performance and durability of the system, which they didn't. Hence the death of step in's. Too bad, because at times a step in binding would be a really good thing to have. Especially for bc travel. But hey, straps are tried and true and I am happy with mine.
