Crockett & Jones | Dark Brown Suede Leather Boston Loafers 。Mens size 10 Boston, a classic penny loafer made from the finest brown suede leather with a single leather sole. From the Men\'s Main Collection. This colourway of repello suede is tanned to be water repellent. Fully treated with ‘Scotch guard’ during the tanning process, the material achieves an exceptionally high level of water resistance to water and oil based substances. This proofing remains effective throughout the life of the footwear although we do recommend you continue with general suede shoe care.
