LATATA is available for free if you build it from source, which requires comfort with the command line, Git, and Python: codeberg.org/sailorfe/latata.

A composable everyday (every night, LA TA TA) toe-up sock knit in 2x2 rib with mirrored wedge toes and a gusset-and-flap heel, in either one color or with colorblocked heels and toes. Besides the gussets and heel, LATATA is intended as reliable, nearly mindless knitting for a wardrobe staple. It currently supports four adult shoe sizes with the premise that you can swap in gusset and heel instructions from different sizes for a custom fit.
