There is no reason to soak as nothing will happen. Any inseam loss can be prevented later on by tugging on the legs so there is no point. APCs come lightly starched so if you soak them, you will lose some indigo and color and the fading will be more difficult to achieve. Soap and water, or an eraser, or anything gets indigo off shoes and the APCs aren't terrible with bleeding like some other brands. I'd reccomend just wearing them out of the box as there are really no benefits to soaking. I still can't find cures, so i guess i'm going to have to just size down 1 on new cures.
