>>6239910These niggas right here. They call 'em tabi feet. They allow their dolls to wear sandals/flipflops/thongs (whatever the fuck your region calls them, because it differs) like that. I have some on my FCS MSD doll, although I don't have any use for them. They don't really impede fitting in normal shoes either. I don't think they make them for DDs, though.
If you bought for a doll from another company, a couple do have optional feet like that for their dolls, but it's pretty rare.
