  • Patent number: 8806688
    Abstract: Footwear includes an upper, a sole, and a thread. The upper has upper holes around the upper peripheral. The sole has a lip portion on the sole peripheral lip portion has sole holes around the sole peripheral. The thread attaches the upper and the sole through the upper holes and the sole holes, and forms a set of stitches. A ripple is formed between two sets of stitches and the thread is embedded in the lip portion between the ripples. Each stitch goes through a first upper hole and enters the sole hole of the lip portion, such that the thread forms an angled stitch on the lip portion. The thread then goes through a second upper hole and exits from a third upper hole, such that the thread forms a horizontal stitch on the inside of the footwear.
