Air Khajiit boots, (just do it )

While you wear these boots, you  add 10  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 your reflexes and agility allow you to move with a burst of speed. When you move on your turn in combat, you can double your speed until the end of the turn. Once you use this trait, you can’t use it again until you move 0 feet on one of your turns.

Notes: Bonus: Speed, Buff, Movement, Utility, Footwear
