"These clothing can cause chaffing and they can cause poor air circulation," Steiner said. "There's nothing yeast like better than a dark, wet place."
Steiner said women need not throw away all their thongs, skinny jeans and the like, just don't wear them all the time.
"The best thing women can do to reduce their risk is to eat a cup of non-fat yogurt with probiotic culture every day," Steiner said.
The price tag on those Manolo Blaniks might be even higher than most women think. As if the high cost of the high designer heels isn't daunting enough, doctors say these slender shoes can cause a chain reaction of foot and back problems.
"Wearing high heels regularly for long periods of time can lead to a contraction of the Achilles tendon," said Ronald Jensen, president of the American Podiatric Medical Association.
Though the extent of a tendon contraction varies, problems with the Achilles tendon can lead to serious walking problems and can be avoided by simply limiting the frequency of high-heel wear.
Jensen also notes that the constrictions high heels put on women's feet are dangerous from a stability standpoint. In particular, balance issues caused by high heels may lead to serious back problems.
High heels cause the wearer to unnaturally tip forward on the balls of their feet, ruining correct walking posture, according to Dr. Scott Boden, professor of orthopedic surgery and director of the Emory Spine Center at the Emory University School of Medicine in Atlanta.
Although he stresses that underlying conditions are ultimately the main determinate of whether back problems will arise, Boden says unusual posture caused by the shoes causes the lower back to rely heavily on the set joints, making the lower back especially susceptible to pain.
For many people, flip-flops seem like the perfect, comfortable, everyday solution for summer footwear. But these staples of summer style have more downsides than you may realize, as their flat soles and open-toe style allow for a number of potential podiatric issues.
Wearing any shoe without proper heel or arch support is potentially detrimental, according to both Jensen and Boden.
Jensen points to the lack of arch and ankle support found on cheaper (and, incidentally, more popular) flip-flops today, and Boden notes a potentially bigger medical issue, known as plantar fasciitis.
"Wearing shoes with little or no heel support can lead to plantar fasciitis, which is basically heel pain, and could require anti-inflammatory shots, or even possibly surgery," he said.
Cheap, flat sandals with little or no shock absorption potential can lead to other serious foot and ankle problems, such as severe tendinitis, that are not easily remedied.
In addition, flip-flops naturally provide no physical protection for the foot from falling or sharp objects. The American Podiatric Medical Association details the dos and don'ts of flip-flop wearing in its recent "Tips to Avoid a Flip-Flop Fiasco" bulletin, stressing the appropriate use and sizing if a person must wear sandals.
"It's OK to wear flip-flops in a poolside setting," Jensen said. "But they shouldn't be worn for yard work or operation heavy machinery."
But Jensen and the association's summer bulletin do both note that a well-structured flip-flop with an appropriate heel is fine to wear under the right circumstances.
