This is a simple slip stitch pattern with a 4 stitch repeat.

The pattern has been written based on 64 stitches, but, the addition or removal of sets of 8 stitches ( 4 on the sole and 4 on the instep) allows a range of widths to suit all feet.

The pattern has a 4 row half pattern repeat and any foot length can be accomodated.

Please note that the length of leg achievable with a single 50g ball of yarn will be reduced for larger foot sizes.
