I also like white boots although I dont own a pair yet.
Personally I'd prefer a bone white color instead of pure white. Pure white looks kinda cheap in my opinion.
I'd also go for a round toe, not pointy. I'd love to get my hands on leather bone color knee high 70's style boots, with a 4 inch block heel (wood color) and a big cuff at the top. Now those would be cool stylish boots. Something like
these Frye "Jane Cuff" boots, only with a higher and thinner block heel that reach up to the knee (17-18 inch shaft) and have a bone/beige color.
