I just returned from the Mayo Clinic in Rochester MN. Dr Wennberg suggested I wear SmoothToe Energizing Socks with 15-20mmHg and gave me a pair. As soon as I got them on I immediately went down to the Mayo Clinic Store and bought a bunch more before returning home. After wearing SmoothToe for a couple weeks I will not wear another brand of SmoothToe socks … in fact… I have now thrown all my other compression socks away. I cant believe how good they make my legs and feet feel. Please keep making these socks and let me know if you come out with brown.
