A: When looking for socks made out of bamboo you expect softness. No such luck with these. They feel like every other set of very cheap elastic filled socks out there only these cost almost seventeen dollars.B: When looking for socks you would think that men's size ten to thirteen would be an acceptable range for a men's size eleven foot. These would not have fit my child when he was 7 years old. Small enough to guarantee elastic lines dug into your skin.C: I searched for socks that specifically had the word smooth in the description only to find out that these have writing on them which leaves open threads inside the sock to dig into your foot. (See photo)Such a waste of money and no time to go through all the rigamarole of paying to ship them back. Buyer beware.
