The heel is turned! The pattern didn't seem to make sense, but I followed it anyway and it all clicked! Yes ... short rows finally make sense! And I am very good at the ssk stitch (one of the ones I was nervous about when I looked over the pattern).
Anyway, off to figure out the gusset ... had trouble picking up stitches along the heel flap as the pattern said I needed to have 19 picked up and I could only find 16 to do it ... but well, I found 3 more and got my 19! LOL!
