In reply to Lukeva:
> I have purchased a pair of 5.10 Anasazi VCS the same size as my Sportiva Katanas. They are a ½ size smaller than my street shoes size. Now, I realise that I should have gone a full UK size down after reading previous threads. Too late!

Your shoes (down a half size) are unwearably painfull - and you think you're mistake is that you bought them too big?! Did you really type/think that?
It's not surprising that you are finding them painfull anyway, Katanas are very big made indeed as rockshoes go. Most folk would size a 5.10 VCS about a full size bigger (as on the shoe label) in order to end up with the same fit so you have essentially bought a much smaller size than you had before by accident even though it will be labelled as the same on the shoe.
As to whether they are to small for you really, then sizing depends massively on personal preference and what you're used to but having shoes that feel crippling is rarely performance enhancing! That said and without wishing to be mean it does sound like you have quite wimpy feet...... It is relatively common for people to fit Katanas anything from 1-3 sizes under street shoe size, depending on how much pressure / tightness and toe crimp they like in their shoes. VCS is normally more like 1/2 to 2 sizes down so you are already wearing them quite "loose" already, relatively speaking.
If you just don't want your toes all curled up in your shoes, that's fair enough too but there are probably better shoes out there than VCS's if that's the foot position you prefer. Something more upright heeled, flat and lace up would a be a good place to go. Trying them on before buying if you hadn't already worked it out, is quite important....
