I read most of the reviews before purchasing this product and I have to say that they all have merit.  IMO, these shoes are reasonably comfortable, but I wouldn't hike in them without socks.  Inserting bare feet, the shoes slightly chafe the inside of my ankle and also around the toes.  This is not too bad, but if you were putting a lot of pressure and wear and tear on them, I think that blisters would develop.  This might be a problem with this style of shoe in general as my really expensive Keens similar to the Crocs Trailbreak will give me blisters if I don't wear socks.  Putting socks on inside these shoes seems to solve these problems.

I am also a bit worried about the strap in the back.  So far so good, but the strap looks and feels a little flimsy.  After being exposed to UV for a few months, I wonder how it will hold up.

The lacing system is also a bit suspect.  Tightening the laces adds support and firmness to the shoe which makes them more comfortable for me.  It is not particularly easy, however, to tighten the laces and exoskeleton. It feels like something might break - the laces or the cinching mechanism.  On the other hand, without the laces the shoes would be too wide for my feet.  I suggest if you are a half size, that you order the lower size rather than go up. I usually wear a 9.5, and ordered a 9 which feels exactly right.

Overall, these shoes are affordable, comfortable, convenient and reasonably attractive - much better looking than the original Croc shoes IMO.  We'll see how long they last.
