Seven-league boots

Seven-league boots are a fictional element in the folklore of Europe. The boots allow the wearer to take great strides -- seven leagues each step -- resulting in great speed. The boots are presented, sometimes old and worn, to the protagonist in order that they may complete a significant task.

Mention of the legendary boots are found in:

• France - Charles Perrault's - les Contes de ma mère l'Oye
• Norway - Peter Christen Asbjornsen /Joergen Moe - Soria Moria Castle
• England - Jack the Giant Killer

Other variations

Boots of speed are a frequent item in role-playing games, and computergames such as rogue-likes of the Moria or Nethack kind:

In the Dungeons & Dragons role-playing game

they are a variation of the famous magical boots. They enable the wearer to run very fast -- usually as fast as a galloping horse, or slower if the wearer is heavy. The wearer must usually rest for long periods after use. The original seven-league boots do not carry this restriction.

In DotA Allstars

they are an item used to increase movement speed by 50. It can be used by any heros and summoned units with inventory slots. It costs 500 gold. It can be upgraded to Boots Of Travel and Power Treads. Boots of Speed does not stack with Boots of Speed, Boots of Travel or Power Treads.
