From Bulbapedia, the community-driven Pokémon encyclopedia.
Running Shoes (Japanese: ランニングシューズ) are a piece of equipment developed by the Devon Corporation. They were introduced in Pokémon Ruby and Sapphire and used in all standard Generation III and Generation IV games.
They are typically received shortly after the beginning of the game, and allow the player to run instead of walk, by holding the B button and pressing the D-pad in any direction. In HeartGold and SoulSilver, this method is overhauled and replaced with a panel on the lower screen that, when touched with the stylus, automatically put on the Running Shoes. However, there are a few places that cannot be run through, such as very tall, thick grass or deep snow. Most caves and routes, though, as well as some buildings, will allow for running inside of them. In Generation IV, all buildings allow running, but deep snow is added in which one can sometimes run but never bike.
The speed at which players can run is about twice as that of walking, yet slower than any of the bicycles.
In Ruby, Sapphire, and Emerald, and Diamond, Pearl, and Platinum, the Running Shoes are given by the player's mother before they leave on the journey. In FireRed and LeafGreen, their mom sends them to the player via one of Professor Oak's aides, who is met after entering Route 3. Finally, in HeartGold and SoulSilver, they are given by the old man who gives the player a tour of Cherrygrove City.
In Pokémon Diamond, Pearl and Platinum, the player can use running shoes inside of all structures instead of being limited to certain buildings in past games.
In the manga
In Pokémon Special, Ruby has a pair of Running Shoes, given to him by his father, Norman, for his birthday. They, like the in-game ones, allow Ruby to run far faster than normal.
