Can't wear your favourite ballet flats in winter for fear of your toes freezing off or your feet sweat profusely in your cotton footlets in summer? I have found the perfect solution. WOOLEN footlets! Wool is natures own thermostat. Up there with double sided tape and the push-up bra, these little woollen beauties will be your own fashion secret to looking chic and staying sleek. They come in black, a lovely natural heather and now gorgeous mineral heather.
