What causes pressure marks even from wearing socks?

Pressure marks from wearing socks can occur due to tight elastic bands or seams that compress the skin, restricting blood flow and leading to temporary indentations. Factors such as prolonged wear, moisture, or friction can exacerbate this effect. Additionally, individual variations in skin sensitivity and circulation may contribute to the prominence of these marks. Generally, these marks are harmless and should fade shortly after the socks are removed.
