In the foot round 1 line, ignore the phrases "on 2nd needle" and "on 4th needle" -- the original pattern is based on keeping the same stitches on the same needles, but I find it easier to base my directions on the markers. So it should be

k to 3 before marker A, k2tog, k1, slip marker, k1, ssk, k to 3 before marker B, ssk, k1, slip marker, k1, k2tog, k to end of round.
