As a shoe artisans from Spain, I would like to explain the differences between Blake and Goodyear construction specifically for dress shoes, such as those worn with suits. These are two common methods used to attach the upper and sole of a shoe and each has its own unique characteristics.
Blake construction is a method in which the upper is directly sewn to the insole and then a thin strip of leather, called a "rib," is sewn around the perimeter of the insole. The outsole is then attached to the rib using a machine called a "Blake stitcher." This results in a clean, minimalistic look on the shoe, making it perfect for dress shoes as it gives a sleek, polished appearance. Additionally, Blake construction is relatively easy to repair and resole, since the outsole is not attached directly to the upper.
On the other hand, Goodyear construction is a method in which the upper is sewn to a strip of leather or fabric called a "welt," which is then sewn to the insole. The outsole is then attached to the welt using a series of stitches. This method is more durable and long-lasting, which can make it perfect for dress shoes as well. It gives a more robust, durable shoe that can withstand more wear and tear. Additionally, Goodyear construction can be used to create more unique and customized looks, while still maintaining a high level of quality.
In conclusion, both Blake and Goodyear construction can be used to create dress shoes and both have their own unique advantages. Blake construction is known for its sleek and polished appearance, while Goodyear construction is known for its durability and the ability to create more unique and customized looks. The choice between these two methods will depend on the intended use of the shoe and the look you wish to achieve.
