Based model is novaSDXL.I found that the current anime SDXL model has very poor recognition ability for ankle socks. The existing LORA is also designed for realistic conditions. So I created my own version. The weight should be at least 0.8. Otherwise, the model will still raise the socks heel above the ankle. When you notice that the model still tends to raise the heel, you can add the "bare ankles" prompt word to strengthen lora.
