Boots of Speed

Boots of Speed are the basic, inexpensive footwear item in League of Legends, granting a flat amount of bonus movement speed. Almost every champion buys them at some point, since mobility helps with positioning, chasing, and escaping.

They are a building block rather than a final purchase: later you upgrade them into a tier-2 boot tailored to your needs, such as boots that add armor, magic resist, attack speed, or tenacity. Choosing the right upgraded boots for the matchup is a small but real skill expression in itemization.
