I am on my feet a lot during the day and by the time I'm ready for bed, my ankles and feet are quite swollen. I have a couple of pairs of calf high compression socks I wear during the colder months, but haven't found anything for the warmer months. Until I found Swiftwick! At the end of the day, I can now see all the details in my ankles and feet, no swelling, no discomfort, no bruising, just simple comfort! Bought the Yellowstone and Rocky Mountain socks, loved them so much, I promptly bought three pairs of Aspire socks. Very, very pleased and absolutely satisfied! Plus, they're made in America!
