When combined with other remedies, compression socks do help reduce pain caused by plantar fasciitis. They put pressure on the soles of your feet, improving blood flow, reducing swelling and inflammation. They could be a great solution if you wear them with supportive shoes during long hours of walking or standing. Many people found compression socks helpful for relieving the pain caused by walking on a concrete floor. However, you should only wear them during the day and never overnight as they reduce the blood flow to your feet. And remember to choose the right size, as a tight sock can do more harm than good.
