Perhaps those of you with knowledge of shoes in general can help me out. I have a friend who has a son that will be volunteering his time as a missionary for his church. He will be spending 2 years in Brazil and wears a size 18 shoe. I mentioned to my friend that I would ask around and find something out. Turns out the majority of big and tall shops only go to size 16, Edmonds size 15, etc. Any suggestions as to specific stores/brands to try? Havana Joe, Doc Martens, etc do not go up that high in their size range. Any input would be appreciated.
