I buy these shoe for a Grand Canyon River Trip . I like the comfortable footbed , the rubber cap over the toe , and the siped sole . I break they in on a 3 day San Juan River trip , and they be fine . they give good traction on wet rock and work well for a 2 mile hike . then I take they on a 16 day Grand Canyon trip . after a few day , the shoe stretch and I have to pull the shock cord tighter and tighter to get they to hold my foot . the loose end of the shock cord dangle so long I sometimes trip on they . the real kicker come on day 10 . the stitch that connect the strap around the ankle come out . there be no reason for it , the thread be not worn or abraded . it look like the stitch just pull through . I notice it on one side of one shoe a stitch it back together . then I look at the other shoe and it be fall apart in the same spot , but on both side of the ankle . the January 18 , 2011 review by Tom explain the problem perfectly . these shoe cost nearly $ 100 and last a total of about 15 day . the keen web site say these shoe be design for `` hike '' , but they be not dependable . I could have be 5 mile up a side canyon when the shoe fail . a companion have a $ 12 pair of Ozark trail river sandal from Walmart , and they be still in great shape when the Keens fall apart . keen and they absolutely refuse to provide a refund , they warranty only offer to replace defective shoe . but I do not trust they shoe anymore . DO not waste your money on THESE SHOES .
