More than 500 women were injured wearing high-heel shoes during the past 12 months - and the renaissance of 1970s-style platforms has put women in even more danger.
The shoes have an ultra-high-heel with a thick platform underneath the toe. Physiotherapists say many women believe it is a great way to add height without extra strain on the arch of the foot.
But musculo-skeletal expert David Woodbridge, from Functional Physio in Mt Eden, said the shoes were worse than a conventional high-heel because the wearer's centre of gravity was raised further and the stability was taken from underneath the toe as well as the heel. "It's like walking on stilts," he said. "It upsets your balance and throws the body weight forwards. There's a risk of acute and gradual-onset injuries."
The taxpayer picks up the strain.
ACC figures show that since the shoes became fashionable there has been a 13 per cent increase in claims caused by high-heels.
