I loved these socks and they were so comfortable, but they didn't last a month.  They ended up with a huge hole in the bottom and then I had to toss them.  If you buy, you need to be careful with them and don't expect them to last a long time. However, I literally wore them out though and washed them alot.  To be fair, it could be my usage... but just be careful - may be best if you wear with slippers.  The company shipped very fast and I had no trouble with the seller.  I didn't reach out to them when they tore up because I didn't think it was worth it for what it was.
