[MR] Need source for men's size 13 shoes

[Aimee Kratts]

Hi,
 
Can anyone recommend a vendor for men's size 13 shoes for 16th century lowland Scot and 16th century English sailor?
 
My stepson is getting into the SCA and while I can make garb, I have to find some place to purchase shoes.
 
Thanks,
 
Amie
