Bought these to replace my very old (about 7 years old) pair of Keen McKenzie's.  It's a very different shoe.  The plus side is that the sole is beefier if you are actually doing some form of hiking. One negative is that the shoe is much wider across the forefoot, as noted in previous reviews.  The lacing system is also a change which I didn't care for when I first got the shoes but got used to after a few days.  Personally, I find it difficult to snug up the shoe as well as you can with laces (I'm old fashioned)  But if I wear a heavier pair of wool socks everything is good and very comfortable and secure. Since the shoe is well ventilated I haven't had any issues with heat build-up. The heel of the shoe also doesn't come up as high as my old ones but as I said with a good yank and an appropriate pair of socks I haven't had a problem with my heel slipping when going on an easy hike/walk.  So all in all they are a decent shoe for the price, which I couldn't find any cheaper than on Amazon.  Would recommend as long as you know about the fit. Personally, I wouldn't use these for watersports because they don't have the close fit I need without socks.  They would flop around on my foot.  Actually, I never thought about using them in the water when I purchased them.
