Pony doesn't seem to understand what "pigeon-toed" means. If you force a generation with a seed image or controlnet it'll do just fine, but it won't respond to the trigger word.
This lora helps force pony to generate images of pigeon-toed people. Weight varies, but it can be used up to about 1.2 with some degradation. Some images were made with highres fix. Faces are a little busted, but I have bad luck with faces in full-body images anyways. knees_together_feet_apart was not trained, but that tag or spread_legs might get you the effect. works from behind, and sometimes while bent over. Any other position YMMV.
