AS the temperature starts to drop outside, it's a good time to start thinking about how to keep the kids warm, cosy and happy this winter.

Whether they’re cosying up indoors or running around at school, warm socks are an essential part of every child’s winter wardrobe.

So if you’re in agreement with Scandinavian parents who say that there is no such thing as bad weather, only bad clothes, read on for our round-up of the best thermal socks for kids.

Thermal socks for your child should offer extra insulation and ideally, a bit of cushioning too, to keep soft young feet comfortable in sturdy boots and shoes.

Most thermal socks are made of wool or wool blended with man-made fibres to improve their durability, comfort and softness.
