Women already fork out for a killer pair heels and now they are also paying for the ultimate accessory - Botox to make your legs look better in stilettos.

Now I have never been opposed to a little Botox here or there but to be honest I think this latest craze is going a little too far.

Dr Wong, of the Sapphire Appearance Medical Clinic who is the only  cosmetic practitioner offering the service in New Zealand , says there has been a huge demand for his calf-thinning services, which involves using large amounts of Botox to sculpt women’s legs and make calf muscles appear less bulky.

It is completed in a single session and, while patients may not see much reduction in the circumference of their calves, it’s all about the shape. The strength of the muscle is not affected, but the procedure does counteract building of the muscle, so it is strictly for the non-sporty.

The cost varies from about $2000, to about $7000, depending on the amount of Botox used.  "It's not cheap and it's not for the faint-hearted," says Wong. But he says it is a far safer option than surgery to achieve the same result as surgery involves removal of the muscle through an incision in the crease behind the knee or, alternatively, destroying the nerve.

Wong has been offering calf-thinning Botox for about four years and sees at least one patient a month. Patients will require a repeat procedure about every nine months to a year to maintain the look.
