I wear quality all leather boots 8" with snake skin gaiters. They are a little warm but not hot to me. I'm good up to just below me knees which is about the same height maybe a little more than rubber boots. They are surprisingly effective at keeping my feet dry even stepping in water over my boots. As long as it's a quick dip I may get my socks a little wet but have been surprised multiple times accidentally stepping in a deep spot or sinking more than expected and coming away not soaked.
