Shoe measurements form in PTR

It is a pretty widely accepted fact that NB shoes run .5 smaller than other athletic shoes (any runners on the forum know that they sometimes wear a full size bigger in Nike and other brand running shoes than they do everyday shoes), so my question is: should DD assume the measurements asked for on the form are for NB and subtract .5 from her regular running shoes? Any advice for the dress shoe measurement as well?

I thought I saw something on a Youtube video that kids were getting feet...
