Comfortable
I put these in a pair of cheap slip on shoes.  They are easy to cut to size and fit perfectly.  They are super comfortable and converted a pretty horrible pair of shoes into a a super comfortable pair.  So far they are holding up very well and have not skid around at all.  It does take a couple hours of walking for these to "mold" to your foot shape, but once they are broken in they remain super comfortable.  Great inserts.
