I read the reviews and bought 1/2 size larger than my husband usually wears and they fit great! They were put to the test last weekend while living in Washington State, it was a real downpour! He was covered in mud and water and surprisingly soaked to his feet! They were dry, I was amazed at how waterproof these shoes are! They are very comfortable as my husband's job requires him to be on his feet and walking 6 days a week for more than 10 hours a day.
