Snake bite and Rubber boots (Lacrosse)

I am getting ready to buy a new pair of boots and I've been thinking about the Lacrosse boots you mentioned. I've always wore normal snake boots but I thought I would try Lacrosse. I think it depends on the size of the snake and the "angle of the bite". I believe a good size adult snake with s direct bit to the foot area would penetrate. I would think a smaller less powerful snake with a "glancing" bite would not penetrate. I know a lot of guys wear these boots. I'll be paying close attention to this thread and I hope you get a lot of answers. The $70 bucks fro the boots is a good price, but one snake bite will have me wishing I paid the $170 or so for the better snake boot.
