I purchase this since I have be purchase the leather one for few year and these may even last longer than the leather one . regardless , I will find out in four year . I own other keen shoe as well since Keen be very comfortable and the toe guard be the best protection I can get on any hike trip or construction site without wear a steel toe shoe . I go through a keen Newport every four year . the leather loose its deep color to a beautiful bleach color since it be continuously expose to water , sun and heat every time I wear keen to my water ski trip . the biggest advantage of keen shoe be its sole . do not stink and I do not have to wear sock so I wear it all the time even when I go to the club and do weight lifting . no other shoe or sandal can ever come close to the comfort , toe protection , expose open surface , no stink sole , durability year after year , use after use in water or land . Bravo .
