Abstract
Abstract The disclosure describes a footlet construction which involves an integrally knitted upper band fitting around the top of the footlet or socklet which need not be assembled from gores and stitching. The socklet is made on a circular knitting machine by using a turned-over top knitted of Lycra yarn on top of a body of nylon yarn. The loops on the elastic top are provided by knitting 30 to 60 courses and preferably about 50 courses on 200 needles with the intervening or alternating needles holding the initial stitch so that a tubular element will be formed serving as the upper elastic band or selvage of the footlet.
