Athletes or Artists? inside the shoe for long periods of time is also the perfect etiology for plantar fasciitis. Dancers, more so than other athletes, are usually unwilling to take time off from their activity to let overuse injuries such as plantar fasciitis heal. Pedorthic treatment for this syndrome, and heel pain, is primarily to decrease pronation and off-load pressure on the heel with elevation. Due the variance in dance footwear, it is more difficult to modify the dancer’s shoe in order to facilitate treatment. An orthosis can be fabricated with a horse-shoe concavity at the heel to specifically relieve heel pain. A good longitudinal arch support and a forefoot post will help control pronation on the medial side. A cuboid lock (support pad) can prevent the foot from sliding off the device laterally. The firmer the shoe, the less stress will be placed on the foot as it tries to flex. As a result, stress on the plantar fascia is limited. Posterior Impingement Syndrome of the Ankle: Dancing often necessitates jumping. In posterior impingement syndrome of the ankle, pain is felt at the back of the ankle when the toe is pointed. This is due to a piece of bone that occupies space behind the ankle, leading to compression of the soft tissues. As this condition is related to pointing the foot, any additional pressure on the Achilles tendon will cause pain. An Achilles notch at the back of the shoe or cutting the backstay of shoe at the top line to relieve pressure on the Achilles tendon insertion may help. Any cut made at the back of the shoe may need to be bar tack stitched to stop the cut from tearing too far down the backstay. Sesamoiditis: Here’s a condition that has been long recognized in dancers. So much so that an off loading pad in the region of the two sesamoid bones that lie beneath the head of the first metatarsal, is called a “Dancer’s Pad.” Pain that develops in the sesamoids can be caused by excessive pivoting or pounding on the first metatarsal head or from poor technique when landing from jumps. In athletic shoes used on hard court surfaces, the incorporation of the “pivot spot” design in the sole under the first metatarsal head has become a standard feature. Most shoes used in dance, other than for practice, will not allow this design feature on the bottom of the sole. Most of the recognized pedorthic modifications that help this condition, such as a good toe rocker to reduce dorsiflexion and reduce weight off the first MPJ, or a well cushioned midsole, may not be possible in dance shoes. When the space in the forepart of the shoe is limited, a thin silicone or Poron® pad under the first metatarsal head will help. Cutting the pad to off-load the sesamoids bones specifically creates the “dancer’s pad.’ Shin Splints (Posterior tibial stress syndrome): Dancers are vulnerable to shin splints as a result of hyperpronation due to leaps and jumps on hard surfaces, improper shock absorption or weakness of the tibialis posterior muscle. Pain at the insertion of the tibialis posterior usually indicates tendinitis or inflammation of the tibialis posterior tendon. A rearfoot varus wedge controls pronation and reduces stress on the tendon and muscle. Running shoes with an overpronation control device on the medial aspect of the shoe would be good advice for everyday wear to relieve pain. For dancers, in most cases, a custom-made orthosis is the most effective method of controlling excessive motion in the foot. Most categories of dance shoes will accommodate at least a ¾ length orthotic. In ballet shoes, a stiff shank and arch support is all that can be offered conservatively within the shoe. If a dancer already uses an orthotic, they should always include the orthotic in any new shoe fitting, as with any other type of shoe.
