Getting started with your Karrimor Running Socks is as simple as putting them on. Ensure your child wears the correct size (UK Kids 1-2) for the optimal ergonomic fit. These socks are highly compatible with all types of athletic footwear, including running shoes, trainers, and everyday active shoes. They are designed to enhance performance and comfort during any training session or active play. For care, the socks are machine washable, making maintenance straightforward. To best preserve their features, including the moisture-wicking properties and anti-odour treatment, wash with similar colors on a gentle cycle. Avoid using harsh bleaches. While they can be tumble dried, using a low heat setting or air drying is recommended to extend the lifespan of the fabric and elasticity.
