No idea why I haven't though of these earlier, these are on my top 5 list since forever... finally! Somehow these are sexy and feminine, not many out there that aren't high heels.
With the thigh boots use negative: leather boots
Trained on all 4 variant, the plain flat sneakers, high tops, knee-highs and thigh-highs. To get the other 2 just don't use the boots prompts, easy.
Recommended str 0.8 and use negative "realistic" to offset the weight even if using with other realistic lora(s).
