I purchased these shoes over a year ago and I have worn them spring, summer, fall, winter at least 3 days a week.  They are not slippery and they are so comfortable.  They look just as good as they day I bought them and I receive compliments on them every time I wear them.  It is fun for me to see the shock on their face when they are exclaiming how cute they are and I tell them they are Crocs...most have no idea Crocs has shoes other than clogs.  I love these shoes and I expect they will last me for a long time based upon how they've performed over the past year.  I have purchased $100 shoes from other retailers and I had to put arch supports in them but I have never had any problem with my feet in these shoes.  I wear them with dresspants, jeans and skirts.  I have the pink ones which are very cute.
