I made MK "Step by step", but without the calculation of the loops, because everything will depend on the size of the foot and the thickness of the thread and hook. I used the rubber sole.
Remove the insoles with crochet using holes that have already been made. Mark the point markers to direct the fixing part, which is associated separately.
Connect the top slippers to the insole.
Continue knitting - knit heel. Use the marker, as depicted, for manual.
Knit the heel back and back to the desired height. Then connect the chain of air loops with a riding slippers.
We continue to knit in a circle (I made three rows), having reduced a few loops on the heel, to make my leg easier. Finish the strapping "rachy step".
Glue the soles to shoes.
