Athletic Shoe Guidelines
Dr. Bender published the following article about the difficulties women suffer with their feet in the 2008 "Women's Health Journal Watch. "
Women's Foot Complants
The most common foot ailments in women are onychomycosis, Morton neuroma, stress fractures and plantar fasciitis.
A variety of foot conditions plague women more often than men. Many are aggravated by the shoes that women wear but also can be caused by loss of bone density as women age. The most common foot ailments in women are onychomycosis, Morton neuroma, stress fractures and plantar fasciitis.
Onychomycosis
A fungal infection of the toenails, onychomycosis most often is caused by dermatophytes (Trichophyton rubrum and T. mentagrophytes) or yeasts and molds, primarily Candida. Although diagnosis often is based on the clinician's judgment, acceptable methods for confirming fungal involvement include use of dermatophyte test medium or a potassium hydroxide test. Onychomycosis results in cosmetically unacceptable nails that are dystrophic, lytic, thick, painful and discolored. The condition can develop as a consequence of tinea pedias, trauma to the nail, an immunocompromised state, or pedicures (removal of the cuticle creates microtears that allow fungus to enter the nail). Treatment options include debridement, oral or topical antifungal therapies, or permanent removal of the toenail with a chemcial or surgical matrixectomy. Simple removal of the toenail without treatment of the fungus will lead to regrowth of the fungal nail. Combination therapy is the most successful approach; for example, results of a 2006 study showed that oral terbinafine plus nail debridement led to higher mycologic cure rates than did treatment with oral terbinafine alone (68% vs. 63%).
Morton Neuroma
This condition develops from enlargement of the third common digital branch of the medial plantar nerve. Pressure from the corresponding third and fourth metatarsal heads and adjacent deep transverse metatarsal ligament causes pain in the third intermetatarsal space. Burning or sharp, shooting pain to the corresponding toes and the sensation of walking on a pebble or a marble are common complaints. Compressive forces on the forefoot (e.g., from wearing shoes with pointed toes or engaging in certain athletic activities) exacerbate these symptoms. A positive Mulder sign (clicking as the neuroma rubs on the adjacent metatarsal heads) can occur on dorsal-to-plantar or side-to-side compression of the forefoot. The diagnosis is best made based on clinical examination or with a diagnostic injection of local anesthetic in the interspace between the metatarsal heads.
Neuromas can also be diagnosed with magnetic resonance imaging (MRI), ultrasound or nerve conduction studies. Other pathologies that can cause similar symptoms are capsulitis, metatarsalgia, avascular necrosis or stress fractures of the metatarsals, soft-tissue tumors, tarsal tunnel syndrome, and plantar plate ruptures. After diagnosis of the neuroma, the patient should be referred to a podiatrist or other foot specialist for evaluation and treatment. Conservative treatments include padding and strapping, orthotic devices and steriod injections. A less-widely used but successful conservative regimen involves weekly injections of a sclerosing alcohol mixture (a combination of local anesthetic and dehydrated ethyl alcohol). In a 1999 study, 82% of patients who were given weekly sclerosing alcohol injections for 3 to 7 weeks experienced complete relief. If conservative therapies are not sucessful, the neuroma can be excised surgically; however, this will lead to a decrease in sensation in the corresponding digital interspace.
Stress Fractures
Metatarsal fractures commonly affect women during and after the menopausal transition; however, athletes and military recruits also can suffer from the condition. The lesser metatarsals are a common location for stress fractures. Patients complain of persistent pain and swelling in the forefoot and might report recent periods of weight-bearing activity (often involving a particular repetitive motion). Initially, the injury is limited to cortical bone - but, if left untreated, the fracture can extend through the entire bone and even become displaced. Although conventional radiographs might be negative for the first 21 days after injury, bone scans or MRIs can reveal the fracture earlier. One study that included 37 female athletes (primarily runners) showed that 47% of stress fractures were identifiable with initial radiographs, whereas 96% were detectable with bone scans. Successful conservative treatment consists of compressive bandaging and immobilization (surgical shoe, cam walker boot, or cast). To prevent fracture recurrence, modification of physical activities and shoe gear should be addressed; in addition, treatment for bone density loss, if present, is warranted.
Plantar Fasciitis
This inflammatory condition of the plantar fascial band (which courses along the plantar aspect of the foot) is one of the most common foot ailments, accounting for 15% of all adult foot complaints. Pain often is localized to the medial plantar region of the heel. Patients report pain when they stand after periods of rest (poststatic dyskinesia). Typically, a brief period of walking offers some relief.
Common causes of plantar fasciitis include foot structure, obesity, changes in physical activity, and lack of supportive shoe gear. Plantar fasciitis is best diagnosed clinically, but ultrasound and MRI often are helpful for visualizing changes in the thickness or continuity of the plantar fascial band. Radiographs can reveal the plantar calcaneal spur that often accompanies this condition. Several other conditions that can cause heel pain (i.e., nerve entrapments, bone cysts, calcaneal stress fractures, systemic arthritic conditions, and lumbar spine disorders) should be considered if the patient has an atypical presentation or is not responding to conservative measures.
Conservative therapy renders successful outcomes in most patients and usually should be employed for a minimum of 6 months. The best conservative therapy employs a combination of icing, stretching, nonsteriodial anti-inflammatory drug therapy, padding, strapping, custom molded orthotics, night splints, physical therapy, steroid injections, short-term oral steroid therapy, or immobilization with a cast or cam walker boot. When warranted, surgical treatments for this condition include open or endoscopic plantar fasciotomies. Newer therapies that show promise but are not yet widely used include extracorporeal shockwave therapy, cryotherapy, and Topaz coblation (radiofrequency technology).
Conclusion
Several podiatric conditions have higher incidence in women than in men. Early diagnosis of these pathologies can lead to more-focused, successful treatment.
Athletic footwear should be fitted to hold the foot in the position that's most natural to the movement involved. Athletic shoes protect your feet from stresses encountered in a given sport and to give the player more traction. The differences in design and variations in material, weight, lacing characteristics, and other factors among athletic shoes are meant to protect the areas of the feet that encounter the most stress.
Well-fitted athletic shoes need to be comfortable, yet well-constructed and appropriate for a given activity. A good fit will mitigate blisters and other skin irritations.
Sports-specific athletic shoes are a good investment for serious athletes, though perhaps a less critical consideration for non-athletes. Don't wear any sport or other shoes beyond their useful life.
A running shoe is built to take impact, while a tennis shoe is made to give relatively more support, and permit sudden stops and turns. Cross training shoes are fine for a general athletic shoe, such as for physical education classes or health club exercising, such as on stair machines and weight-lifting because they provide more lateral support and less flexibility than running shoes. They also tend to be heavier than running shoes, but most people don't need light, flexible shoes for cross-training. If a child is involved more heavily in any single sport, he or she should wear shoes specifically designed for that sport.
Our practice recommends sturdy, properly fitted athletic shoes of proper width with leather or canvas uppers, soles that are flexible (but only at the ball of the foot), cushioning, arch supports, and room for your toes. Try a well-cushioned sock for reinforcement, preferably one with acrylic fiber content so that some perspiration moisture is "wicked" away.
Athletic shoes need to be replaced after one year, whether or not they are worn, and after a certain amount of repetitive load is placed on them and wears them down. The American Academy of Podiatric Sports Medicine advises replacing running or walking shoes after 300 to 500 miles of wear, and replacing aerobic, basketball, and tennis shoes after 45 to 60 hours of wear. Athletic shoes should also be replaced if they show signs of unevenness when placed on a flat surface, display noticeable creasing, and/or when the heel counter breaks down.
