Love my socks! Due to extensive surgery on my leg I only have the Tibia supporting my ankle which creates a great deal of instability when I walk and also means there is none of the natural shock absorbtion two bones normally provide, the socks help to support the muscles and tendons through the full range of movement. As a bonus, the compression in the socks also aids in boosting the circulation in my leg and helps to ease some of the nerve pain caused by the surgeries. So a win all around for me and allows me to stay on my feet longer. You never know, I might be able to climb mountains after all.
