the thing is I am more concerned over the look compared to the size.
I think they look enormous in your final picture. Not only that, the way the shoes droop around your foot when they're laced makes it totally clear they are nowhere near your size.
I had to get rid of pair of Ravello short wings that were .5 to long and one width too wide. It was hard to do but that pair fit me much much better than yours appear to fit you. Just bite the bullet and send them off to someone else. Consider it an act of good "Alden Karma".
I can somehow make the sizing work with an insole, but don't want them to look too big and unproportional.
size-wise, only you will ever notice the difference between 11 and 12. other people will not notice. you might not want to wear ultra slim trou with them. otherwise the two sizes will look the same i think to most people. you can definitely make the sizing work with an insole. these are boots. but, the concern i would have, is that the shell ripples are going to be vicious on shoes that are not well sized for your feet. they could be looking like a pair of turds pretty quick. shell veterans (i am not much of one) can correct confirm or correct this opinion, but i am pretty sure that a poor fit will produce more deep and pronounced ripples. with calf the extra distortion from the poor fit is not as big a deal in boots. all you get are more fine wrinkly lines.
I'd say, if can use and insole and they feel good, keep them. My wing tip boots fit similarly around the vamp but are pretty comfortable. It allows me to wear a thicker sock, which I think is quite normal for boot wear anyway. The key, though, is how do they feel to "You?"
don't know if this is the right thread for this. these are recently purchased preowned alden ravellos wingtip boots. really beautiful but the thing is that the size is a good half size bigger than my Indys 405 (11.5C). I can somehow make the sizing work with an insole, but don't want them to look too big and unproportional. what to you guys think? thanks in advance.
It's just my opinion but those are too big.
I have never, ever been happy with a pair of shoes that weren't the right size. No matter how beautiful they were.
I know it will be hard to say goodbye but I would send them off to the next guy.
