Have you had your foot properly measured? Just because you wear 10.5 in "every other shoe, golf or not" does not mean those are the right size and width for you. If these shoes crunch your toes you do not have the right size/width.
I wear FJ Icons, and like many here I have taken them from the box and walked 36 holes with nary a single blister. Ever. So I know my sizes are spot on. And there is no break in period for a properly sized pair of FJ's. Get to a FJ shop and have your foot measured properly and get the right sized shoe and your problem will be solved.
