Hard to tell from your photo but they don't look off at all to me. I'm an 11D brannock and wear 10.5 in my Vibergs as well. I never understood the concern that boots look too big in larger sizes. Maybe if you were at 12-13 but IMO 10.5 looks fine. With that said, if you don't like the look, you don't like the look. I always thought the IH 310 makeups looked great but I'm not skinny like you. My jeans always end up with a 8.5-9" hem because of the waist size.
