This pattern is very similar, yet distinct, from mosaic 27. I’m even using the same yarn! (Albeit with a different main color. The yarn is Oink Pigments Targhee sock yarn.) To make sure they had something obviously different, I decided to have a striped, reinforced bottom. Between the inherent squishyness of this yarn and the reinforced bottom, the sock should have lots of cushioning!
In terms of actual heel shaping, I made sure to turn the heel in such a way that it was 24 stitches after turning. These 24 stitches became the bottom of the sock, and the stitches I picked up along the side became pattern stitches. It isn’t super obvious with this pattern, but then what I did was to decrease at the border of pattern and bottom. I did a slower decrease than I’ve been doing on the small little reinforced heel triangle of the previous sock (#27). Here I decreased every four rows, i.e. the first black row of a black row stripe (in mosaic knitting you do two rows with one color before switching out for the other color). The foot is a bit big on me, but I think my feet are also on the small side in terms of circumference, so I think they should fit someone else really well.
