These pull-on rubber boots are made more like a wet suit than a standard rubber boot. The bottom shoe part is semi-firm and waterproof and the high part is somewhat porous like a wet suit. If you are a scuba diver, picture the wetsuit booties with a firmer shoe part. They are really comfortable and very easy to pull on and off. If you don’t go in water over your ankles, they keep your feet dry. The porous uppers mean your feet don’t get clammy and stink. They make doing chores on a wet day so much better. They are so comfortable I think I could hike in them, although I have not tried it.
