I wonder if the feet of sex dolls are so detailed?

I would like to adopt a sex doll. I have visited in several places and found several places I like. But the choice is not obvious. I have a lot of questions on my head, the size of the vagina lips, what is the ideal size of a doll for men over 1m80, but the main question I asked myself was that some of the feet ’s feet in the TPE are very detailed, I want to know Is the doll’s feet so detailed? In short, I hope to find a shoe. Are silicone sex dolls so detailed? Why are the dolls in tpe not so detailed, so their feet are realistic?
