These soft-soled boots look comfortable and quiet.

You can activate boots of desperation only when your current hit point total is equal to or less than half your full normal hit points. When activated, the boots grant a +30-foot enhancement bonus to your base speed and a +5 dodge bonus to AC against attacks of opportunity. These benefits last for 1 round.
This ability functions three times per day.

Prerequisites: Craft Wondrous Item, expeditious retreat.
