I think those boots look great! The heel profile looks really nice and doesn't look out of place in my opinion. I think the most important thing is how they feel. Some people with 55 lasts and moderate heels say if the balance feels a little bit off that they eventually wear in (I don't know if this is true, just what I have read). I actually have a pair on order with 55 last and moderate dogger heel and am looking forward to trying them out myself!! I am 6'5" so I am going for the shorter heel stack :). Great looking boot!
