These decrepit looking boots actually hold a powerful magic, and a significant curse as well.  

When attuned to these boots the wearer gains a +10 to walking speed.  In addition, the wearer is allowed to Dash or Disengage as a bonus action three times per short rest.

However, when resting, the wearer must make a DC 14 Constitution save.  If the save is failed, the wearer gains one level of exhaustion.

Notes: Bonus: Speed (Walking)
