These shoes are great. They are comfortable and light-weight and are not clunky looking like the traditional crocs. Note that the berry colored version looks more purple than in the picture. I also have the navy blue. I wore the navy blue to work this morning and never took them off once I got in. No one noticed (or at least no one said anything).

I bought these shoes because my heels hurt in other flat shoes. My heels felt significantly better in the crocs but my knees ached a bit as I walked. I think the knee issue was probably due to my legs adjusting to new shoes though.

I really suggest these shoes. They're affordable and comfortable.

[Update] After about a year with these shoes, the traction on the bottoms have eroded to the point that I can't wear them in the rain or accidentally walk on any wet surface on the street lest I slip and fall on my butt. I would be really careful with them after 6-12 months... and I didn't even wear them for a straight 6-12 months. I would estimate that I wore them for 5 months alternating with other shoes.  You expect at least a little trouble when walking on wet surfaces in any shoes. However, I have slipped in these on sunny days when I didn't see a puddle in front of me. They are inexpensive but I expected more from CROCS. I have reduced my rating from a 4 to a 3 star.
