My husband and son say that these are the most comfortable socks they have ever worn.  What they like best about them is that the bottom of the sock has cushion and excellent arch support (both of them are flat-footed so arch support really helps provde comfort);  the top of the sock is a mesh type of fabric that they say feels like a "breeze" blowing across your foot all day.  They say that regular socks made their feet sweat but these do not.  The price is a little high but if a pair of socks can make someone feel that good all day long, they are worth any price.  I will keep them supplied with these socks as long as they are available.
