I haven't read all the posts so someone may have covered this.
Snake boots up to knee. Bass Pro did have some with nice looking with excellent chestnut leather feet and canvas tops that breathed but no snake could get though it.LL Bean and others too.
Several of the better Outdoor magazines have ads of excellent shooting attire and boots for snakes and brush country. Suitable for fashionable wear anywhere including horse.
Then there are the English boots that predate cowboy boots up to the knees if they say snake proof. Really put the dog on.:)
Shooting Classics, Cowboy and Indian and similar mags some times have those ads.
Then a .38 or 357.or.44 our inch barrel or 6 inch, or 2 inch, or whatever suits you with a six or 7 shot, in one Ruger .357 model, single ro double action and holster to match boots and belt etc. I like my old 2 inch Nickle Colt Lawman MkIII .357 in forward cant holster by Bianchi with snake shot.
