From Zelda Wiki, the Zelda encyclopediaLink utilizes both the Pegasus Boots and his sword, resulting in a headlong forward dash, sword drawn and held out in front, ready to skewer foes in Link's path. It appears in all games featuring the Boots. Although it can be used to attack foes, the attack is generally named in-game for crashing into trees to knock useful items from their branches.
A Link to the Past
In A Link to the Past, this attack will be used automatically whenever Link uses his boots. Unlike in its other appearances, this attack can occasionally be used to open some cracked walls, a feature normally reserved for Bombs.
In Link's Awakening, both the boots and his sword must be equipped, but the sword can be slashed instead of just thrust during the attack. If the sword is unequipped, Link will simply dash forward unarmed. Unlike other games, different weapons can be used in the dash attack, like Link's Shield or Bow.
The Minish Cap
After obtaining the Pegasus Boots in The Minish Cap, Link must visit Swiftblade to learn the Dash Attack. The attack will be automatic whenever Link uses the boots afterwards, but before he learns it, he will just run headlong without touching the sword.
