I am very pleased with the comfort. Is already my second Merell few, the last had to suffer greatly on our construction site so I then gave myself a new pair. Solely from the "water permeability" I'm a bit disappointed. If you work in a high wet grass for several hours but you get wet feet. However, I had otherwise always the problem with sweating, I do not know what is of both unpleasant. I have not found a better shoe.
