never liked to look but bought a pair of cheapo knockoffs and wear them around the house, they walk great but the knockoff plastic in the upper is a little stiff so ordered the real deal  based on reviews.  Cost 5 times more money in the local store, about 35% less on AMZ.  The knockoffs are a US Mens 10 so ordered mens 10.  Well, they were so large they would not stay on.  Plastic is much more supple so I was sold on going with the Crocs.  Went to local store and tried mens 9 which felt fine so sent 10s back and ordered  a 9 but they are very small. Fit more like an 8 shoe.  They are so small my toes dig into the front.  So sending those back.  Great for walking and comfortable but even though they are obviously molded in one piece there must be differences from machine to machine, plant to plant or something.  I read that these will shrink in sunlight perhaps the 9s were sitting around a while an shrank?  Very disappointed and now another return back to Amazon.  Seems I'll have to go local to find a pair to fit.
