Hello, I suffer from poor circulation and my hands and feet always get really cold :( I have been wearing 2 pairs of socks and suede boots but my feet are icy!! I don't really want to buy Uggs unless I am sure they will keep me warm. Any recommends? I know it's nearly spring now but I can't bear the thought of having an icy-toed winter again come the end of the year and want to be well-prepared! I have seen Merrell boots recommended and Dubarrys, again v pricy.. are they worth it? Thank you!!!
