Here's a pair of Wellington boots I made for V4 a while back. They're a little rough, since they weren't for a close up or anything. I made them conforming with AutogroupEditor and Quick Conform because I thought about putting them in freestuff, but never got around to texturing or finish tweaking them. As is, they just use the standard Poser leather shader.

Looking at them again, I believe a real person would have a hard time getting their foot in or out of them. :)

There are a lot of helper applications out there to make the job easier.
