I wear North Face Thermoball indoors when it’s cold, I also get foot pain from cold floors. I do find them too hot in the warmer months so wear Crocs indoors now.I became "UGG curious" a short while ago.
I've not had slippers since I was about 11, but our house has mainly wooden floors and I was getting some foot pains that I thought might be related to feet on cold flloors throughout the winter.
I must have given UGG my email address at some point because I now get multiple emails from them every single day. They're bloody relentless.
