Those would probably do fine, but I usually try to get taller boots.

Under $100, that's pretty easy. The best deal I have found would be these:

I don't worry about weight to much, but that's just me. Just as long as the boot is comfortable and warm.
Check out Cabela's, gijoes, campmor.com, sierratradingoutpost.com.

Good luck.
