I would research the internet. I've read somewhere that the shin type might not be high enough. Also, I live in Auburn, Alabama and Auburn University is doing a study and found out that rattlesnakes are now sometimes not rattleing to warn you. Another nifty fact. 50% of snakebites east of the Mississipp are copperheads. Rattlesnakes generally warn, you are also more aware of cottonmouths around water. Copperheads are hard to see on the woods floor with leaves. Good boots is a must. I quit turkey hunting early in the mornings in the spring because of snakes, especially going out before daylight.
