I practically live in these, and I need to buy more colors haha.  Seriously, I've owned other crocs before, but nothing compares to the comfort of these wrapped clogs (except the wrapped mary janes, which are also amazing!).  The black ones stay clean looking and presentable, I have the lilac too but they show droplet marks on them easily.  I will say if you wear a half-size, as I do, order the next size DOWN, not up, you'll get a much better fit (especially since you can wear these without socks, but even with socks these fit fine) - I ordered the lilac in the next size up and they're visibly too long and my feet move too much in them, but I ordered the black in the next size down which looks and feels perfect.  I'm an MT student so I'm on my feet a lot, and these are wonderful for that too (the wrapped mary janes are a little more secure for MT due to the movement required, but these certainly keep my feet super-comfortable so I can be on my feet and not be worn-out and grouchy before my next client :)
