Re: New game - sims feet are blue, not wearing shoes inside
@KashmirG2002 I take it those aren't just some weird clingy socks you've downloaded? This is probably bad custom content, and you'll need to sort through your Mods folder to get rid of it. If you have a lot of cc, the 50/50 method should speed things up considerably.

Sometimes even removing bad cc alone isn't enough to restore sims to normal, so you may need to create a new sim to test whether the bad file is gone.
