I love fun socks, but it seems they are always too tight. I'm a size 9.5 to 10 shoe. I never knew about Extended Fit socks until browsing the Joy of Socks website. Now I can have fun socks that fit comfortably at affordable prices! I really love these paw print socks, my four-legged children are a big part of my life. I'm glad I bought so many pairs and will definitely re-order more in the future.
