I found it impossible to convince Flux to generate small feet in big oversized shoes, especially in sandals where the feet are visible. This Lora is meant to fix this. You can now prompt for sandals with a lot of empty space around the foot.

Lora weight has a certain positive correlation with how much oversized the shoe is.

Typical prompt:

realistic scene of a woman wearing oversized shoes, she is wearing too big sandals, oversized shoes extend beyond her heel and toes, short small feet in too big sandals
