Shelling out $680 for Isabel Marant's ubiquitous hidden-wedge sneaker was, until recently, the only way for a woman to add height to her frame without wearing heels.

But the French designer finally has some competition. A new product called Invisible Heels is set to give women the same 'invisible lift' - for $19.

Made from a sturdy contorted base, with a double memory foam upper cushion for comfort, the product enables women to add 1.5inches to their height using any pair of shoes they want.

Invisible Heels promise to 'accentuate the legs and achieve an overall slimmer, sexier, more confident look' by adding 1.5inches to a woman's height

'We wanted to create a bouncy effect without it being too "soft" - and while keeping its sturdy shape. Achieving this balance was key,' said 33-year-old French-born, New York-based founder Pierre Jeand'heur. 'The more you wear them, the more comfortable they become!'

FEMAIL tried the wedges over the weekend to put Mr Jeand'heur's claims to the test, and surprisingly our shoes felt more comfortable with the Invisible Heels than without.

'It felt like my heel was cushioned in a pillow,' said one staffer.

The wedge inserts, which promise to 'accentuate the legs and achieve an overall slimmer, sexier, more confident look,' work in shoes above the ankle only - like boots and sneakers, where the wedge can be concealed.

Priced at $19, the wedges are made from a sturdy contorted base, with a double memory foam upper cushion for added comfort

However Invisible Heels is working on a lower version for spring, with about half the current height to adapt to low top sneakers such as Stan Smith, Van's, and other flat summer shoes.

Mr Jeand'heur admitted that it was his wife's addiction to the Isabel Marant Beckett sneaker that pushed him to create his own Invisible Heels wedge.

'She loved these sneakers and had them in all colors,' he said. 'But she wanted to get the same lift and elevation in her Ugg's and Hunter Boots as well as leather Hermes boots'.

So he started working on prototypes at home with blocks of foam and came up with the first version of the 'invisible heels'.

'Once my wife started wearing them at work and on weekends, all her friends asked if they could get them! It was insane! So we decided to find a manufacturing partner and produce them "professionally."'
