Wondrous item, uncommon (requires attunement)
While you wear these boots, you have a flying speed equal to your walking speed. You can use the boots to fly for up to 4 hours, all at once or in several shorter flights, each one using a minimum of 1 minute from the duration. If you are flying when the duration expires, you descend at a rate of 30 feet per round until you land.
