We have had a pair of these for a year and five year-old won't wear them. I got them because they're the same as the ones his Dad has and they are very warm, soft socks for winter inside wellies (although you might need to get wellies a size bigger to fit the socks in!). For some some reason our little boy refuses to wear them. He doesn't like the look of them and says they are 'itchy'. They're not itchy, but they are fluffy inside - I guess he doesn't like fluffy! I got a pair of Regatta walking socks for him instead and he adores those. They are not so bulky, but also warm and cushioned.
