I'm also struggling with this pattern. Iv done the first section including shaping the instep but can someone please explain:
With right side facing, rejoin yarn at base of instep and pickup and k13 sts along side of instep, k across centre 8 sts, then pick up and k13 sts along other side of instep. 34 sts. Beg with a p row, work 5 rows in st st on these 34 sts.
