I’m also using the heel pattern from the “toe-up fixation footies” because I didn’t like the heel pattern from the knit picks pattern. It just seemed like a lot of extra work for nothing.
For the right foot since the toes were angled I took half the stitches off the needle and placed on a holder while I worked across the back half for the heel. Then on the last row I knitted them back onto the circular needle that was holding the other sock so that both socks faced their appropriate directions. Then I placed the held stitches back the front needle accordingly also. Now both socks on 2 circs face the directions they would if I were wearing them. Now I’m knitting in the round on 2 circs again for the cuffs.
I had to rip back to the heel and add some stitches between the heel and top stitches because the stitches got really big and made a gap between the stitches. So I ripped back and added 4 on each side, then completed the socks one at a time. I used “jeny’s super stretchy bind off” method… But I wasn’t impressed. I can get them on and off and they maintain their structure, but its really not That stretchy. So I think when I make these again (which will be soon) I will try something else.

I couldn’t find a bind off that I liked, so I finally ripped out the binding and sc the stitches. It works great!
I’m knitting another pair of socks with this same heel and I realized my mistake on these.. I didn’t pick up 2 wraps on the stitches, so it caused a gap. I’ll have to beware of that next time!
