Are the boots actually large, or is the Darwin figure small?
Large. The body is about same height as normal truetype but with very narrow torso.
Are these the largest boots on a ThreeA "human" figure available?
I think so, I haven't come across anything bigger.
Are HT hands compatible with ThreeA bodies?
Yup, 3A bodies are pretty much true type.
Are the boots readily compatible with HT bodies?
It should. The ankle and foot uses the same system as true type.
Are they pegged boots, or do you put "feet" in them?
There are feet in them.
I'm thinking of buying one of the Darwin figures, because I'm curious about ThreeA products. But if I could simply buy the boots, I might go that route & maybe save money
If you are interest. Send me a pm for the whole figure.
