Gaiters

put them on when it's chilly in the morning, and take them off into your pocket once you get going. They weigh next to nothing and replace long sleeves or trouser legs, making them great for running and cycling. Shoe gaiters are a category of their own: they stop snow, mud and small stones from getting into your shoes, and in winter in deep snow, they are practically essential. Choose based on the attachment: a strap under the shoe and a lace hook hold better than just elastic.
