This easy to use, inexpensive and comfortable device is designed to keep tension on the plantar fascia or Achilles tendon so they heal in a stretched or lengthened position at night.

A comfortable night splint your patients will wear: While night splints have been shown to be an effective treatment for plantar fasciitis, patient compliance has been less than enthusiastic due to their cumbersome nature. In a recent study published in the Journal of Foot and Ankle Surgery, Dr Lance D Barry found that the 89 patients who used the Sock had a mean recovery time of 18.5 days with 97.6% recovering within 8 weeks. In addition, none of the 89 patients were unable to tolerate the Sock. The Sock consists of a tubular knit material with two adjustable straps. One is secured above the calf and the second runs from the toes through a ‘D’ ring just below the knee to maintain the foot in a neutral to slightly stretched position. Advantages : Doesn’t interrupt normal sleeping; Easy to use and adjust; Stretches the entire plantar fascia; Doesn’t restrict the ankle joint; Takes full effect of windlass mechanism. The Sock comes in two sizes: Regular fits calf size to 40.5cm around, and Large fits calf size 40.5-53cm around.
