I know nothing about these shoes.  I am told they are deep sea diver footwear shoes.  They are embossed Billard.  They are cast iron.  Each one weight is 4 lbs. 3 oz.  I cannot find a size on them.  They look to me to have been painted the black but it might be original.  The straps are good and look to be nylon.  From back to the toe the shoe is 11 1/2".  Buyer to pay s/h calculated in USA.  Email with questions.  NO INTERNATIONAL BIDDING.
