We purchased these last June 2014, as a birthday gift. First, we were sent the wrong sandal and now after recieving the correct one, we find that by this June 2015 the bottoms are seriously coming unglued from the sandal. We live in North Idaho, so they have not been worn through the winter but rested in the closet. We are very disspointed with the quality of these Z/2 Yampas although several folks in our family have owned Chacos for years and haven't had this problem. Perhaps it is the more agressive sole on these?? Anyway, these aren't worth what they cost.
