1st row (after ribbing) knit:
knit with Another Color (AC): 3 sts knit (knit the first one too), 1 st slip (yarn behind work) and so on. Knit to the middle: before CS lift one stitch from the previous row and knit it "twisted", then slip CS without knitting, yarn behind work; again one "twisted" from the previous row; 2 knit, 1 slip (yarn behind work), 3 knit sts and so on; at the end 2 knit sts and 1 purl st.

5th row, knit (knit with AC)
Knit like the 1st row. and so on.
When there are 7 stripes of OC and AC (i.e. there should be 97 sts on the needles)

Next, knit 2 rows (knit and purl rows) with AC, then with OC. Next, we move on to the sole. The principle of knitting is like in the "7 out of 7" socks: I knit like this. 54 sts; 2 together knit; turn the work, 1 slip, 11 knit sts; 2 together purl; turn the work again, 1 slip; 11 knit and so on. When there are 5 stitches left on the sides of the needles knit not 2, but 3 sts together knit like this 3 times. When there are 9 sts left on the needles, pull the thread and sew the back seam
