National Red Sock Day is observed on the third Saturday of February, aiming to raise awareness about Peripheral Artery Disease (PAD), a condition that affects blood flow in the legs. The day encourages individuals to wear bright red socks, symbolizing healthy circulation, and to spark conversations about the often subtle signs of PAD, such as cramping and pain. Activities include sharing information online, organizing community events, and advocating for regular health screenings to promote early detection of PAD. The initiative was launched by The Way To My Heart, a nonprofit group, to highlight the importance of recognizing and addressing PAD before it leads to more serious health issues. The red socks serve as a bold reminder of the need for awareness and action regarding vascular health.
