When you're out on winter walks, stay warm from the feet up with these long boot socks. They're crafted from supersoft cotton that's cosy and breathable, with a chunky ribbed texture for extra toastiness. Pull them up to your knee to slip them into your wellies, or scrunch them down for a relaxed feel. Choose your favourite mood-boosting colour, complete with vibrant contrasting cuffs, toes and heels.
