Blake Rapid Stitch is a construction technique which is like a hybrid between Blake stitching and Goodyear welting. A double sole is sewn to the upper. First, the traditional Blake stitch construction is completed, then a second sole is attached with an exterior seam.
Blake stitching is done with what is called the “single stitch” method. The shoe’s upper is folded underneath the insole, and then stitched into place with a single thread connecting the insole, the upper, and the outsole on the inside of the shoe – as can be seen in the diagram left.
All of the components are stitched together by hand through a special machine, called a McKay machine, which lock-stitches the thread to ensure it won’t come apart.
The Blake Rapid construction results in a more solid construction that is still flexible and sleek. The shoe is relatively waterproof and it is possible to replace the outsole without the need to influence the insole and upper part.
