With boots, you can pick any 2 out of the following 3:
Good lightweight boots are expensive, cheap lightweight boots aren’t good and good affordable boots aren’t light.
Also - no hiking boot in history has actually been waterproof. Keeping water out in snow is a lot easier, but when it comes to rain and dew, I have tried many different brands, different waterproofing products and many types of gaiters - and water always gets in eventually. Usually within 3 hours at most. Incidentally my experience with gortech boots has been no better than leather for staying dry, just the boots don’t last nearly as long.
Read accounts of pro climbers on big mountains, even their R20k mountaineering boots don’t stay completely dry.
