In reply to TobyA:
Thanks for your reply. That's interesting because the UK site does not give the same info for the quantic and SF models. Why do manufacturers not do this- or at least pick up on it when their website designers do it.
The Quantic has an FKS last but no picture of the sole shape- which the SF does have, but no last identifier.
Given how important fit is, I find it difficult to understand why they don't allow you to filter for most characteristics - split sole, asymmetry, stiffness, width etc etc. They certainly have all that data.
