Another perspective for your consideration: I've long since given up on waterproof boots for anything short of ice climbing or skiing. In all other circumstances, my feet sweat enough so that socks and inners are watersoaked by the end of a day, rendering waterproofing irrelevant. Even when climbing on snow during warm weather—I ski tour in the mountains during summer—I often wear running shoes on the way up. What does it matter if my feet get wet, as long as I'm warm and in no danger of frostbite? Even if they get cold, they warm up readily in any sort of reasonable weather.
During rare situations in which I really need to protect my feet from water penetration from the outside (extensive wading of cold, snowmelt streams, for example), I merely put cheap plastic bags over my socks. Trekking in Africa or Asia, I prefer lightweight trail shoes or trekking sandals.
An exception would be if you are planning to trek at high altitude, where frostbite really is a possibility. If so, please ignore all of the above.
Furthermore: as you know, YMMV.
