The frequency of replacing grip socks depends on factors such as usage, wear and tear, and the quality of the socks. In general, it's a good practice to replace them when you notice signs of wear, damage to the grips, or when they no longer provide sufficient traction. Regularly inspect your grip socks to ensure they continue to serve their intended purpose. Joe & Bella's Everyday Gripper Socks is made of durable, high-quality fabric that should last many washes.
