I *love* these. They are crazy comfortable, warm, easy to wear in cool and cold weather.
A few things - Be careful when you remove the liner. The first time I did it, I broke the button. (Crocs replaces these for free)
Also, the white liners get funky FAST. Even if you wash them they still quickly look worn and matted. They do not sell the liner separately so you can't update them. Next time I'll get Black.
Regarding how very warm they are, that tends to not be the case after one season of hard wear, now that the liner is matted and been washed twice they are not overly warm and can be worn in spring. They're still comfortable, but I'd prefer the option to buy a new liner! 4 stars

These were purchased as indoor/outdoor slippers. I have used them to even run to the store in! They are extremely comfortable and warm. I have taken the lining out and washed them - make sure you follow the laundering instructions - they can't go in the dryer - and to remove the lining was quite easy! 5 stars

I liked these shoes so much I boght everyone in my family a pair for Christmas. They are very warm with the liners in so I only suggest wearing them on a cold day. 4 stars

I have been looking at these for awhile, and finally found some to try on in a shop. I thought these would be great for winter. They do run small because of the lining, so I did go up from a 9-9 1/2 to a 10. I wanted something that would be lite weight, they are, and something easy to clean, they are, but- they still have holes in them. We have a lot of rain here. Would these be practical? Hmmm....Maybe not. I tried them on and they are SO WARM. Even in the winter here, I think they would be too warm for me, especially with socks on. The pink ones really looked like slippers to me, the black ones were better, but after really wanting these, and finally trying them on, I have found I really don't want these after all! Glad I did not buy them. I will keep looking for the ideal shoes! 3 stars

This is the first pair of Crocs I have ever bought, on the urging of a friend. I must admit that he was correct that these are the most comfortable shoes I have ever worn. Being diabetic I have a difficult time finding comfortable shoes, but these sure fit the bill. I am planning to purchase more Crocs. 5 stars
