Very disappointing!! When first received they were a bit on the large side; roughly one size too big. Unfortunately, I left them right outside the sliding glass door--for the ease of putting on and off when going in and out of the kitchen-- came out this morning only to find out they have shrunk by at least two sizes. When I left them outside yesterday the temperature was approximately 75 degrees and last night it got down to 65 degrees; not excessively hot or cold. This is ridiculous. The whole point of having outdoor clogs is so they can be left outside, especially after working in the yard and they are covered with dirt and mud, Last time I will be purchasing Crocs. Unless you want to wear these indoors, stay away; check out other brands that don't shrink!
