I would recommend them
“Having not worn them previously I was unsure if I had the correct size. Even though your size chart was specific I crossed over in ankle size and calf size. That was just a small issue and are very happy with the size I finally chose. Have not worn them on a long flight as yet. I would recommend them. Calculating the right size is better than grabbing a pair that only has a shoe size at a pharmacy or similar outlet. Comparing them to the ones my husband grabbed at the airport prior to a previous flight I would have to say your ones seem of much higher quality. Your customer service is outstanding. It was like getting a gift from a friend. ”
