The only complaint I have with these socks - durability.  I started throwing socks away after only 30 days due to holes forming in the heels.  The toes and heels are not reinforced.  The socks were comfortable, but with daily wear all were in the trash after 7 months.  With the high cotton content of the socks, I would buy the socks again if the durability was greatly improved.  Until that happens, I can not recommend them to anyone.
