Being a paraplegic I deal with super cold feet from lack of circulation, not to mention the down time in bed.  I needed a sock that was super warm and had good cushion.  I found it!  I love these and cannot wait to buy more.  They aren't too binding at the top so I have never had to deal with a cutting off of the circulation.  They have just the right amount of compresion for me for night time.  The cushion also provides me with some "extra" padding to combat sores on my heals.  I would reccomend these to anyone and am planning on buying more.  For me the "season" doesn't matter as my feet are always cold.  I've tried other socks and end up pulling them off in the middle of the night because of heal pain.  This has not happened once since I've begun wearing these super socks.  They are a little costly but I bit the bullet and am so glad I did.
