I order this pair of shoe for my husband 's birthday . he be a 10w so I order a size 10.5 think it would be plenty big . my son have a pair of Keen 's and they run true to size . well I be wrong . so I follow the instruction on the shipping label I get from Backcountry -lrb- a Amazon vendor -rrb- to exchange they for the next size up . Backcountry credit the return , but do not notify I that they received\/processed the exchange . when I call to ask if the larger size be on the way , they say since it be purchase through Amazon they would not pay the shipping on the way back . so now I be out $ 12 for return shipping , no shoe , and very disappointed at the lack of coordination between Amazon and its vendor . I will not be order anything like this on Amazon again !
