These cut into my calves and leave indentations. They are very comfortable in the foot area and provide excellent arch support. I will not be able to wear these on my 2 week hiking trip due to the compression around the calf. I tested them this weekend on a shorter trip and it was unbearable after 3 hours of wear. Unfortunate, since the sock had exceptional breathability and moisture wicking. These did fit the calves of my 12 year old niece. I would say if you have shapely calves, these are a no go. If your calves are thin or straight, these would be a great purchase.
