the BEST sandal that I have ever own . I buy my first pair of keen shoe about 3 year ago . and my first sandal a year ago . I have walk hundred of mile in many different environment . be a world traveler in many ` developing nation ' , I highly recommend a ` closed toe ' shoe . you never know what hazard you might come across . with my Keen 's I always feel safe . and comfort ? they be the best ! I be in my fifty and ` always ' look for shoe that my foot , knee , hip and back be happy at the end of the day . if there be one dislike ... it would be the odor from sweat . a world of difference from my old Teva 's , but still a bit of odor from the h2 . and honestly , my foot do not typically smell . something with the sole of the shoe and sweat . even so ... I will purchase another when the day come to toss my current pair . from the look of it , that be a couple year away .
