The Allen Edmonds lasts
Allen Edmonds construct shoes on a wide variety of Last. Lasts are foot-shaped forms that provide shoemakers with a foundation for building a shoe. By selecting shoes manufactured on the Last that most resembles the contours and nuances of your feet, you can enjoy a superior fit while enhancing the performance and comfort of your shoes. Allen Edmonds' shoes are constructed over each Last using three different methods, welted, handsewn and cemented construction.
A welt is a strip of leather sewn around the upper and insole of the shoe to which the outsole is then attached. Apart from its durability, one advantage of stitching the components together using a welt is that it conserves the leather’s natural flexibility and allows it to breathe. A welted construction also allows for the shoes to be recrafted and therefore extends the life of the shoe.
In this process the upper is created by fitting a single piece of leather around the underside of the last and then stitched to the plug by hand, using needles and waxed thread. A leather midsole and sole are then attached by machine stitching to produce a remarkably comfortable and flexible shoe. True handsewn construction allows the shoes to be recrafted and therefore extends the life of the shoe.
The sole is attached directly to the upper using a special adhesive and without the use of a welt. Cement construction is a superior method for attaching rubber soles used in many casual shoes, such as sneakers. Shoes made using the cement construction method cannot be recrafted.
