The sock-shoe trend has been around for a couple of seasons now but it's well and truly at the forefront of fashion footwear (say that three times!) this current winter. The sock heel or sneaker is fun and comfy and adds a cool conversation piece to your outfit. Wear with long skirts/dresses, culottes, skinny trousers or long shorts.
