I wanted a slide and this is the second one I have gotten from Amazon.  I have never had a problem with my feet sweating (quite the opposite) but when I wear these my feet sweat! It must be whatever it's made of.
 Oh how I wish I could get a pair of Made in the USA cotton or terry slides, I am having such bad luck with these Made in China slippers.
I gave the slippers 2 stars because they are some what comfortable (although my feet sweating isn't).  Maybe it's just me (who my doctor always worries about because I never sweat - maybe I should wear these slippers the next time I see him) but if these slippers were cotton terry or some kind of breathable material, I wouldn't have this problem and would like them.
