Alden Black Cordovan Longwing – Frans Boone Store。From Alden of Washington D.C. - Long Wing Blucher in Ravello Shell Cordovan (a very special color from Horween that is difficult to create, hence its rarity). Full glove leather lined with pure vegetable tanned leather insoles. Double oak leather outsoles with Tan \"Antique\" edges and Dovetailed heels. Barrie last. Shoe trees NOT included. Very lightly worn, always with trees in; never worn in the rain. Beneath the insole is a layer of cork, providing additional resilience and insulation. Every Alden New England shoe carries a tempered steel shank, precisely contoured and triple ribbed for extra strength. Truly the backbone of a fine welt shoe or boot, the shank provides the proper support and shape required to give comfort throughout the day. Oak tanned leather bends are cut into outsoles at factory for maximum control of quality. Alden shell cordovan shoes are finished by Alden\'s master craftsman. They are admired by the finest boot and shoemakers throughout the world. Using the centuries-old method of pure vegetable tanning and hand finishing, the single tannery (Horween) still producing genuine shell cordovan today is indeed practicing a rare art. The tanning process takes a full six months to complete and produces leather that is soft and supple, yet very durable.
