Truly lightweight and also warm enough for 10 degrees is a tough combination. I wear U.S. made Danners with 800 gram Thinsulate when the temp is below 30, more or less, if I’ll be sitting. Not especially light nor cheap either. Since I only wear them hunting, it’s a lifetime investment for someone my age. Good boots are worth every penny. You can’t hunt effectively if your feet hurt or are cold. The American Danners can be sent in to be repaired or resoled.
Foreign-made boots are cheaper and may work very well, but may be throw-aways when they need fixing.
