I would like some zippered boots too, but sadly they are not authorized with Marine Corps uniforms. A work around I use is to get Danner or whatever boots you like with speed lace eyelets. They are the ones that have large loops for the laces to go through so the laces can be tightened fast. Then, put some lace-locks on them. This makes it almost as fast as a zipper since you don't have to tie the laces. I use the Nite Ize brand and they work as advertised.
