Wonderfully comfy.  They breath well becasue of all the holes in the insole and on the top of the shoe.<br />Squishy insert sole.  Wish they had a bit better arch support (I have reeeally high arches)... but these are luxurious to wear.<br />If your feet, heels, arches or knees hurt.. these are a God send.  Best to buy a 1/2 size larger.  Great price too!
