I wear these approx 4-5 hours a day everyday, sometimes more, on my farm. They are genuinely waterproof (unless submerged or its a torrential down pour and it runs in the top) but still breathable. I am in FL so in the height of summer sometimes my feet get a bit sweaty but that's unavoidable, its really hot. Because I wear them so often and have a gait abnormality, I go through a pair in about 4 months, typically the interior lining shreds and becomes mishapen so they no longer fit correctly or the sole will separate (which I just shoe glue back together for a time). They are very comfortable for doing all kinds of chores and walking and climbing on my farm as well as hiking, even in loose sand. I have good traction wet or dry ground. DO NOT ever ever put these on a boot dryer or it will melt the plastic waterproof liner inside and they will shrink up to only fit tiny children's feet. Stuff them with papertowel or newspaper and let them air dry! I like the choices in colors, I've had the red, green, and blue, plus they offer a wide footbed, very comfortable.
