Pierre Allain was making climbing shoes prior to the 1950's but in the 50's Edouard Bourdenneau, expert shoemaker, buys P. Allain’s business. He keeps on manufacturing the climbing shoe that now wears the initials EB on a round piece of leather next to the malleolus. This is the first time a brand is put on a climbing shoe, a major turn in the history of “climbing” shoes. Bourdenneau shoe store is made of four rooms: a store at the front, in the back of the store Mrs. Bourdenneau is doing sewing, and there are two other rooms, one for cutting and one for mounting rubbers. Shoes are still made under the EB name today.
