The Right Compression Sock The result was MDSOX. Using their medical knowledge and experience, Dr. Furlong and his team were able to develop a compression sock that actually did what it was supposed to- it improved the lives of his patients. As he saw MDSOX make a noticeable difference in his patients’ lives, he began to think about how others could benefit from the use of effective compression socks. Not Just for the Medical Field The answer proved simple. As leading vascular professionals, Dr. Furlong and his team knew that compression socks encouraged the flow of blood to the legs. While vascular patients use the compression socks for therapy, this same effect could help athletes, people with active lifestyles and professionals who are on their feet all day.
