Yep Iron, these are fantastic boots. Unfortunately, I don't think your size 14s would be happy in these size 12s.
I think they are cut a little larger than the indicated size. Otherwise, I would not have them for sale. I would rather have my boots a little loose than too tight but two sizes off may be too much. If you wore a size 13 they might work.
If these don't sell, I will be OK with keeping them because they are just a tad wider than I need. It's all I can do to keep from putting them on and taking a ride but since I have them listed as new they will stay that way unless I remove them from the classified forum.
Thanks for your interest and comments.
