Does anyone now the sizing difference between startrite and clarks shoes?

[pirategirl]

Have a pair of 11f shoes put by for her here, that I bought in January but they were much too big. She was in a Clarks 10 1/2 at the time.

Startrite comes up a 1/2 to 1 size larger, so a 10 1/2 C would be a 10ish S

so could b up to a size bigger, thats a huge difference.

they could be an 11 1/2 or 12 yes.
