I bought some of these socks and yes, delivery was exceptionally slow. They do look okay and no problems with loose/hanging elastic as others have mentioned.
Worse thing about them (and I bought 'mountain' and normal styles) is they feel very coarse and uncomfortable, as if made with string - not soft at all. Strangely not noticeable when wearing shoes/boots but just around the house. May well become softer when worn in and washed with softener. Not especially warm either.
Overall not the luxurious soft and warm socks I was expecting but okay at the price I suppose.
