I had a big supply of Thorlo thick cushion hiking socks which were too thick for some shoes.  These moderate cushion crews are just right and helped some athletic shoes that do not come narrower than A2 fit and feel better.  My foot is very thin with no padding on the bottom and calouses build up, but wearing these socks help so much.  They hug my foot and do not bunch up or wrinkle in shoes.  They are well worth the price for me except I wish the top edge were like the hiking socks.  These may not hold up as long because of the top edges.  The hiking socks have stayed nice after many years. Also, because the foot part of the moderate cushion fits snugly and the part above  the ankle is looser, sometimes ankles puff up but my athletic shoes may be the cause.  They are still so much more comfortable than other socks and I wear them so much need more pairs.  My foot doctor recommends Thorlos in an instruction page he gives patients.
