These are a slight variation on the classic Crocs clogs. In my opinion they look a little bit better but I did not notice any difference in how they are built or how they fit and feel. I've owned quite a number of Crocs shoes/flips/clogs over the years. These are my 4th pair of Crocs clogs - I've owned 3 pairs of 'classic' (I think they are called "Beach" clogs) and one pair of lined clogs that I use as slippers in the fall and winter.

I normally wear 8/8.5 (41-41 European) but I ordered 9 in these and they fit well. With Crocs clogs, I found that it works great for me if they are a little bigger than normally. 8 fits a little small.

The things I like about these are:

* EXTREMELY comfortable
* well built. Can last forever UNLESS you expose them to extreme heat like for example leave them in direct sunlight for days.
* they float
* excellent material. Unlike 'normal' plastic these have great feel
* excellent ventilation for hot summer days
* dry fast and can be used in wet conditions. Although these are not sandlas or clogs for serious 'water use' like hiking in a wet environment etc. They can become slippery and do not secure your feet! These crocs can be used for lightweight hiking (I use them) but if you are into serious hiking there are other clogs/sandals that are much better. I can recommend the Keen sandlas as just one example
* super quick to put on and take off
* light weight
* provide some toe protection

There's really nothing I don't like about these, excep the fact that they are VERY casual so you can't wear them anywhere you go. It's very much like flip flops. I would say you can wear these whenever you can wear flip flops...
