In reply to Dom Whillans: I have wondered what the VS stands for, "velcros" presumably but the S is a bit confusing.
Perhaps it means that you're not allowed to use them on anything easier than VS because, frankly, that would just be embarrassing to all concerned.
I'm reviewing some Sportiva Cliffs for UKC at the moment, and gear editor Kevin is doing the Miura VSs. I'm going to have some comments on their name, I wonder if Kevin will?
