Winged boots

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.
The boots regain 2 hours of flying capability for
every 12 hours they aren't in use.
