These running socks require no complex setup; simply put them on. Ensure the correct junior shoe size (UK 5-6) is selected for an optimal ergonomic fit, which is crucial for comfort and performance. Ensure they are pulled up smoothly without wrinkles for the best fit inside shoes. ### Care Instructions - Washing: Machine wash cold with similar colors. Use a gentle cycle. Avoid hot water to preserve fabric integrity, elasticity, and the effectiveness of the Fresh Guard treatment. - Drying: Tumble dry on low heat or, ideally, air dry to extend the lifespan of the socks and maintain their shape and fit. Avoid high heat drying. - Bleach/Iron: Do not bleach. Do not iron, as high heat can damage the synthetic fibers and compromise the anti-odor treatment. - Storage: Store socks in a dry, well-ventilated area.
