High-heeled shoes slant the foot forward and down while bending the toes up. The more that the feet are forced into this position, the more it may cause the Achilles tendon to shorten. This may cause problems when the wearer chooses lower heels or flat-soled shoes. When the foot slants forward, a much greater weight is transferred to the ball of the foot and the toes, increasing the likelihood of damage to the underlying soft tissue that supports the foot. In many shoes, style dictates function, either compressing the toes or forcing them together, possibly resulting in blisters, corns, hammer toes, bunions (hallux valgus), Morton’s neuroma, plantar fasciitis and many other medical conditions, most of which are permanent and require surgery to alleviate the pain. High heels – because they tip the foot forward – put pressure on the lower back by making the rump push outwards, crushing the lower back vertebrae and contracting the muscles of the lower back.
If it is not possible to avoid high heels altogether, it is suggested that the wearer spend at least a third of the time they spend on their feet in contour-supporting “flat” shoes (such as exercise sandals), or well-cushioned “sneaker-type” shoes, saving high heels for special occasions.
