Boots of the Dunerider (5e Equipment)
From D&D Wiki
Wondrous item, rare (requires attunement)
A pair of leather boots, dry and cracked, with crude wings composed of sandstone shards on the sides. If the last thing you do on your turn is moving along the ground, you start your next turn with your movement speed doubled. This lasts until you take an action, receive damage, or are otherwise interrupted, at which point your movement returns to normal. While you stand on sand or sand-like material, you ignore difficult terrain and your movement speed is doubled; these effects can stack to triple your movement speed.
