For many runners, music is as much a necessity as sneakers. A colorful and lightweight iPod shuffle ($49) holds hundreds of songs and offers 15 hours of battery life. The clip-on feature means music comes sans pockets or armbands, making it a cinch to use. For a special touch, you can even upload a workout playlist for the runner in your life — they're sure to think of you the next time they're out for a run. Check out our running playlists for some serious song inspiration.
