TIPS:
Boots do not come in half sizes.
Mens boots are larger around the leg, so are more suitable for ladies with athletic legs. Go down two sizes when converting womens boot sizes to mens.
Zodiac classic high boots are rated to - 40º F / - 40º C so you only need one pair of good-quality thick socks.
Add sock liners if you are prone to cold feet.
