Alden's Long Wing Dovetailed heels feature full glove leather lined flexible pure vegetable tanned leather insoles with double oak leather outsoles. Unsurpassed for breathable comfort and long wear, it assumes over time the contours of your foot shape giving a truly custom quality to the fit. 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.
