Idem means repeat.

Cuff rnds {1-4) x5, k 1 rnd, begin chart.
After the heel I was confused as to moving on and had to think about it for several days before it made sense to me. First cut CC2. Then using MC and CC that were left hanging, knit across instep rnd 1 chart A, pick up 18 sts to heel continuing chart A. Follow gusset chart for heel. (I had 20 heel sts so only 1 decrease on first decrease rnd.) Pick up another 18 sts and continue same row from chart A. BOR is where it always was. After gusset is finished, decrease to 70 sts. When foot measures 6.75” change to CC2 and do the toe as usual. End chart A after rnd 11.
