I think that cowboy styled boots are among the most wearable boots around, if you can find them. The World of High Heels web site has several styles of pointed-toed knee high, OTK, thigh high, and crotch-high cowboy styled boots available. They also have many other high heeled shoes and thigh boots, all available in standard and larger sizes. One or two people on this site bought boots from this website. I am considering a pair, as well.
