Blake stitching is one of the first mechanized methods of shoemaking. It is a simple,
quick and cost effective way to make shoes by utilizing a stitch that goes
through the insole, uppers and outsole.

Reed Blake came up with the in 1856, . His specialization was shoemaking and in
fact worked for the famous Singer Sewing Company. Later on he sold the patent
to Gordon McKay, hence the alternative name.

For a blake welt, the upper is wrapped around the insole and attached between it and the outsole. A single stitch attaches everything together.
Because it is a simpler construction than a goodyear welt, it is also less expensive. It is a process that allows for resoling once the outsole is worn or damaged. Blake welting is also superior when seeking a close-cut sole. Because there are no exterior stitches, the body of the outsole can be cut extremely close to the upper. Lastly, because it has fewer layers than a goodyear welt, a blake-welted sole is more flexible.
