I've had a pair of Russell turkey hunters for about 30 years and they would be perfect for anywhere in the South, especially where you are likely to encounter snakes.
If you buy a pair you should get them perhaps one half size larger to accommodate a warm weather sock, like wool. If I were to order another pair I would ask Russell to make my uppers about 1/2-3/4 of an inch larger so that I could tuck my pants legs into them more comfortably.
I also have Russell's Safari boot; the low cut thing that you can wear without socks. I'm going to send mine back to Russell and have them replace the hard rubber sole with plantation crepe.
Russell's might be a little more expensive but you'll forget that after you've worn them a season.
