I purchased a pair of Crocs Mammoth shoes for my daughter and they are a disappointment.  Our family loves Crocs and we all wear them, so I never gave it a second thought when purchasing these.

My daughter loves how comfortable and warm these shoes are and she wants to wear them daily.  That's the good part.

The bad part has been the odor.  When she first started wearing the shoes, it was not too cold yet and she did what she always did with Crocs...put them on without socks.  BIG mistake.  The shoes started to stink so bad that you could smell them while standing next to her.  So, I went through the difficulty of pulling out the liner (as other reviews have said - it is a struggle) and following the care instructions.  I washed them on cold and let them air dry.  No results - still stinky.  Next I washed them on warm and let them air dry - still no good.  Last time...I washed them on the Sanitize cycle and let them air dry.  This time the odor was gone.  However, the nice fluffy look of the lining is now matted and the shoe fits larger since the volume of the lining is smaller.  Additionally, the liner is starting to rip in a couple of places at the seam.  I'm not sure if this is from the wash wear or from daily use, but I can tell this product won't hold up as well as I'd hoped.

Since sanitizing the liner, I have had my daughter always wear socks with these shoes.  That seems to help quite a bit - so my advice is ALWAYS WEAR SOCKS WITH THESE SHOES.

Overall, I am disappointed that these shoes aren't as great as the Beach, Cayman, Cloud & Mary Jane styles that we have.  I was willing to pay $40 for the Crocs Mammoth, but now I wish that I had spent less on a copycat version so I could replace them as needed this season.
