Knit toe up with magic cast on with no knot, magic loop on one 2.5mm circular, increase up to 56 stitches, 1.5 repeats across the top of the foot, mirrored for left and right foot, short row heel, 3.5 repeats around ankle, half repeat on the inside/back of each leg also mirrored, five total repeats in length of foot, five in ankle. The sizing mods were for the sportweight yarn, otherwise they would have been too big and I knit them toe-up so I could squeeze the maximum number of pattern repeats out of the yarn.
