This was my first time to wear crocs but had requested them as a Christmas gift because of the cold tiles on my floors.  They do a wonderfull job protecting my feet but I must say it has taken me at  least 3 days before the STRONG ordor of fumes to leave the shoes.  I put them in the garage overnight and when I opend the door all I smelled was the shoes!  It was very strong and I don't know if this is the usual case or not, it didn't seam like I noticed anything in the store when I tried them on but the ones from Amazon were over powering.  The ordor hasn't completly left but is getting better.
