This seamless slipper pattern fits most adults. The actual size is determined by the length you knit. Since they have no seam, they are comfortable to wear.
It begins at the heel and is knit partially back and forth and partly in the round.
Bulky weight wool or two strands of worsted weight held together
Size 8 US (5 mm) double pointed needles
Gauge: 3.5 to 4 sts=1″
When slipping stitch, slip purlwise.
Soles (Optional) I use something called replacement carpeting sold at auto stores and some big box stores. Several layers of denim, wool, or other sturdy material may also be used.
