Blake & Rapid processing is a technique that allows you to stitch together the midsole and the sole in leather. Through the seam you can achieve higher strength of the base.
Blake it is a simple process of joining the sole directly with the shoe’s upper with a large strong stitch. This makes the sole thinner than the Goodyear welted shoes because they do not need an intermediate layer connecting the shoe sole to the shoe upper.
Blake-Rapid is a synthesis of Goodyear and Blake methods, where the stitching technique of blake is combined with the extra midsole of the Goodyear and greater isolation from the outside.
