Boots of Speed

While you wear these boots, you can use a bonus
action and click the boots' heels together. If you
do, the boots double your walking speed, and any
creature that makes an opportunity attack against
you has disadvantage on the attack roll.
If you click your heels together again,
you end the effect.
When the boots' property has been used for a
total of 10 minutes, the magic ceases to function
until you finish a long rest.
