Getting cold feet

The lowest parts of my body often feel rather cool even though I have typically been keeping the temperature in the house up at 70°F. I bought some warm-looking slippers with fake sheepskin or fleece or whatever all around the inside and they are an improvement. I wonder if I need thicker socks. Though, probably not thermal: I do have thermal socks and they are a pain to wash, their interior lining can't take heat. Perhaps I should try wearing two pairs at once. I am warm in bed at night, all wrapped up in blankets. I linger in the shower because the hot water feels so good.
