Also on boots make sure that she tries on every pair within your city limits and beyond. I am on my third pair of boots already because of issues with them. Have her walk around the house in them for a little while as well, break them in before she straps in. It'll save her a good amount of pain.
As for suggestions, 32 boots are the best feeling but I couldn't wear them because of my calf size, Salomon makes super comfy boots as well, that is what I am in, a pair of Salomon Optima's. But she will have to try on a whole bunch before she will really tell the difference.
