Pinkelnder Gartenzwerg

This pattern is worded very differently to every other crochet pattern I’ve ever done.
Example;
2 sc in each 2 sc (12)
Instead of;
1sc, 1 increase x6 (12)
The font used also makes it difficult to read.
Once used to the way in which it is written it’s worked very well so far.
However I’m currently stumped on section 8 which reads; crochet 20 sc on top of the shoe
But which row to start on?
Which stitch on that row to start on?
What stitch to use to join the thread to the work? And where do I place each of those 20 single crochets?
Photos provided show how the shoe should look but give no clue as to where to start and finish these 20 single crochets.
