I do not write many product review , but I think I would chip in my two cent to help the next guy . I love these sandal for they comfort and fit . I wear they on a couple of backpack trip with 40 lb on my back tromp through stream along the way , and I never have the slightest hint of a blister on my foot . my review of three star be four three reason : First of all , they only last about 18 month . keen have a 12 month warranty , so do not expect they to outlast that by much -lrb- my day-to-day use be more sit in a cubicle than backpack through wet terrain -rrb- . second , they be heavy . these weigh a multiple of you standard flip-flop sandal and probably more than you tennis shoe . Third , and this be probably more I than the shoe , they tend to get very stinky . I do not know if they need a wash out hole in the toe or what , but they tend to build up gunk in the toe and really smell up the house . all in all , I would buy another pair , but for the price you should be able to expect more durability . they be cheaply glue together and will start the clock to fall apart the moment you put they on you foot .
