Not sure why, but they are too small.  I have another pair I purchased at a local store that are the same size.  These are too small and the others fit great.  Both pairs state that they are 8w- 10m.  I didn't choose to reorder at this time b/c I'm not sure I will end up with a pair that actually fits the way they are suppose to with their current stock.<br /><br />Otherwise I love these shoes.  The one problem with them is that they heat up quickly.  This does make your feet sweat, which I can live with.  The real downside to the heat is that they attract dirt and dust.  After wearing my other pair around the house for a few hours I end up with lots of debris in the heel and toe area.  It is very strange.  I have worn other brands of foam type shoes, i.e. Crocks, LLBean, etc and this has never happened before.
