In reply to Dandelion:
I would suggest that if you're wearing Katanas you either don't have wide feet or you're not wearing very well-fitting shoes. Sportiva themselves say they are one of the narrower shoes they do.
If katanas DO fit and you like the shape - buy TC pro's in half to one size up (it's the same last just stiffer).
If actually you're wearing 38 katanas and your street shoes are like 38-40ish, and you think you do have wide feet, then maybe try going into a shop and trying on a selection of Scarpa shoes. For all day trad, have a look at the Techno X, Force, and maybe the lace up (stiffer) version of the vapour?
