I am using these in the winter for house shoes, wearing socks with them (I live in Germany).  I have plantar faciitis so I always need to have a shoe on, one in particular that I can easily slip into or out of.  They give me great support.  I normally wear a 7.5 or 8, but the 7's fit perfectly.  If you have a very narrow foot, I would not recommend them.  Look forward to wearing them as a sandal in the summer.
