I often see items I pick up to add to the wardrobe I use for shoots.  One item I am really unsure of is shoes.  I see some great shoes at fantastic prices, but what would be a good size to get that would fit most models?

My mom, sister, myself, and all my friends are from 7.5-8.5

8 is good

Thanks, in fact a model I am buying some shoes for is a size 8 -  Thanks.
