Bought these Keens on sale for an excellent price, just before going on a cruise to the Southern Caribbean.  They fit so comfortably, and dried quickly when they got wet.  I didn't experience any of the problems other described regarding discoloring of feet, etc.  May have been the particular color I purchased. No blisters caused by these shoes at all, and they worked well for ziplining, which required closed toe shoes. Have never had Keens before, and saw them recommended on CruiseCritic by several regarding shoes that do well when climbing rocks around waterfalls, etc.  They have lots of grip and are not bad looking for athletic shoes! Couldn't be happier.
