My winter boots are a 48, eg UK13
And I've owned Katanas in a 42 as well as Evolv Pontas Lace in 45 and 46(the latter is a bit more comfy). I've bought all my shoes locally and I would say shape is also a big factor.
Look at what shoes, not just climbing, have fit you well in the past and go from there. Climbing Anchors seem quite good at ordering sizes in too so maybe try them. |
