Bought these for my husband so this review is from him. He has purchased these boots before and wanted another pair because he was so pleased. He wears standard width size 15 boots. These Hi-Tec boots truly are waterproof. His feet have never gotten wet while wearing them. The tread holds well on all kinds of terrains. He leads photo workshops in Yosemite National Park so he needs great hiking boots -- and these work well for him. The first pair lasted years, can't remember when he bought them. We expect just as great a performance from this pair.
