I've been searching for a pair of boots that zip up the back--not a specific label, just any pair--and have found exactly two, in two years or so. The first pair was a Wellington-styled brown boot from Coach, which held little appeal for me. Priced around $270. The second pair I found was a Calvin Klein boot with a half zip/buckle on the back, black, runs about $450. My question to anyone is can you recommend any other makers of the backzip, and if so, what's your take?
