Abstract: A shoe includes a sole and upper secured to the sole. The upper has a knitted element formed of unitary one-piece construction on a knitting machine. The knitted element includes a Moc seam allowance within a toe region, lateral and medial metatarsal regions, and lateral and medial ball regions. The upper has a Moc seam formed in part by the knitted element. The Moc seam is in at least the toe region, the lateral metatarsal region, and the medial metatarsal region. The Moc seam includes a core around which the Moc seam allowance is wrapped and stitched to itself to contain the core at least partially within a cavity formed by the Moc seam allowance.
