The Running Shoes (Japanese: ランニングシューズ Running Shoes) are a piece of equipment developed by the Devon Corporation. They were introduced in Pokémon Ruby and Sapphire and have become a standard feature of the core series games.
In the games
The Running Shoes are typically received shortly after the beginning of the game. 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 in Pewter City, right before entering Route 3 and after battling Brock. In HeartGold and SoulSilver, they are given by the old man who gives the player a tour of Cherrygrove City. In Pokémon Black and White, they are given by the player's mother after the player first ventures onto Route 2. In Pokémon Black and White 2, they are given by the player's mother after the player is introduced to the Pokémon Center by Bianca. In Generation VI, although the Running Shoes are no longer a distinct item, the player is still wearing them from the start of the game (as noted by a Hiker in Vaniville Town in X and Y) and can use their running ability at any time.
The Running Shoes allow the player to run instead of walk when they hold the B button and press the D-pad in any direction. In HeartGold and SoulSilver, this method is overhauled and replaced with the Sprint Button, a panel on the lower screen that, when touched with the stylus, automatically puts on the Running Shoes, allowing the player to run without having to hold the B button. 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, instead of being limited to certain buildings as in past games, 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 (8 steps per second in Generation VI). Attempting to dodge Trainers with the Running Shoes will attract the attention of the Trainer and cause them to face towards the player. Additionally, running through the tall grass increases the chance of being attacked by a wild Pokémon.

In the Pokémon Adventures manga
In Pokémon Adventures, Ruby has a pair of Running Shoes, given to him as a birthday present by his father, Norman. They, like the in-game ones, allow Ruby to run far faster than normal. The manga also explains that the Running Shoes use compressed air to propel him.
