This hexagon slipper has a double thick sole and is made up of 3 motifs per slipper but if you wanted to make them into slipper boots just add 2 more motifs at the top of each slipper attaching in the front and back V and sides.
I did take into consideration some of the other peoples reviews that have worked up these slippers and rounded off the toes on the last 2 rows by sc2tog at each end. Also the instructions were not that clear on the hook sizes for the different shoe sizes, I used a 5 for these pairs ranging from size 7 female to size 10.5 male. The adjustments in shoe sizes were made through the sole sizing. But if you were to go any bigger than I would suggest going up to a 5.5 or even a 6 with a tight tension.
