This is my third purchase of 'Old Friend' slippers.  I am diabetic and these slippers are a life saver.  Besides that they are the most comfortable slippers I have ever had. I purchased one pair for my son and he fell in love with them immediately.  They are not only comfortable but they do not make my feet sweat even in hot florida summers.  Could not recommend a pair of slippers that are more comfortable and versatile.  FIVE stars!!
