Sole Thickness: 8 mm = 0.32 inches.

If a rubber Vibram sole is added to this sole construction, the thickness of this sole will be 12 mm = 0.48 inches.

The Blake-Rapid construction can be described as a continuation of the single leather Blake construction. It adds an outsole, covering the Blake stitches underneath. To properly attach the outsole, Rapid stitching is introduced around the perimeter of the midsole and outsole, producing a welted look like that of the Goodyear. The first sole is sewn from the inside together with the upper and the insole, while the second sole is joined to the first with a seam outside, obtaining improved isolation from the elements, making it easy to resole, comparable to the Goodyear welt. This means that the thickness of the Blake Rapid sole mimics that of the Goodyear welt, generally a minimum of 8 mm, making it sturdier and weatherproof, while enjoying a low cost and efficient stitching process. Resoling is easy as detailing the outsole does not affect the structure of the Blake Stitch underneath.
