My 14 yr old needed socks to wear with new boots and these fit the bill nicely.  They are long enough to reach his knee and thick enough to keep the boots from rubbing his legs.  The reason they only have 4 stars is the trouble my son has figuring out which way is up. Without a dedicated heel spot, sometimes they go on upside down and get bunched up.  After a few wearings, the heel spot is stretched out but it does make it a bit awkward at first.
