I have these boots in brown. This will be their 4th winter and they are as good as the day I bought them. I wear them constantly - the brown goes with everything and I can walk miles in them. Can't recommend highly enough. Have reheeled once.
Nospringflower. I agree with the poster who said you should ring Duo. That's not right and I'd be surprised if they don't stand over them.
Love Duo boots and am trying to talk myself out of a new pair this year as I need other bits and bobs more!!
