The socks are great and very warm, although the soles do wear out rather quickly, but they are definitely not knee-highs, as pictured. I don't have a large calf, but these barely came halfway up from my ankle, and were well below my knee. I'm only 5'4" tall, so I don't have a long leg either.
Previous slipper/shoe purchase from Eddie Bauer and they were 2 years old & washed countless times. This pair has holes in the heels & bottom already less then 2 months old. Very poor quality & good craftsmanship is non existent. Buyer beware!
This sock has an inner liner for warmth. However, the liner and the outer knitted portion are not attached to each other, so putting the sock on becomes difficult because the two are not going on together. I ended up returning this as it was a gift for my daughter-in-law and just putting the sock on was difficult and tedious.
