The PF Sock


The overnight treatment of plantar fasciitis based on Strassburg Sock.

The Strassburg Sock is well-know for its treatment of plantar fasciitis, due to the patent of Strassburg Sock will expire this year, so we have studied and improved it, try to make a better quality version.

How it work?

The Strassburg Sock is the soft splint that sets the plantar fascia to its optimum length. The device consists of a tubular knit material and adjustable strap system. It is easy to use and is designed to keep tension on the tissue, so it heals in a stretched position at night. Most other night splints only set the ankle at 90 degrees and provide no toe dorsiflexion. Then at the patients first step in the morning the plantar fascia is stretched and the pain returns. The device takes full effect of the windlass mechanism of the plantar fascia to position it at its maximum anatomical length therefore it could relieve pain in the stretched position. In this way, many patients find a reduction of their morning pain.

2)improve the stretch pull system

The complains of Strassburg sock is sometimes it only pull the fabric around the toe, not the toe directly. In order to improve this, we added a less stretch film in the bottom of foot, this will make the pull system extend to the back side of foot. After testing, the toe dorsiflexion is better than the original style and thus improve the patient treatment.

3)damage of Velcro 

Considering the hook may damage the fabric, we simply change the position of hook and loop.


Reduce the chance of allergy.
