A device for performing ankle-based inversion therapy, based on the method established by gravity boots. The device includes a mounting component at its top which enables attachment to support bars, while the primary loop of the device is adjustable in size and conforms to the ankle. A handle and extension are used to enter the inverted posture and to open the primary loop upon exit. Grip loops on the outside of the primary loop are used to manipulate the device with opposite toes during use.
