Shadiya Omar, 22, attacked Justin Lloyd, also 22, after he began arguing with her friend as they both waited for a taxi home after a night out in Manchester city centre.
Manchester Crown Court heard Mr Lloyd approached Omar's friend outside the Mercure Hotel in Piccadilly Gardens on October 18, 2014. He offered the woman a crisp but she knocked them out of his hand, so he attempted to pour the packet over her head.
The court heard Omar reacted by rushing to her friend's aid and struck Mr Lloyd in the eye with the designer shoe.
Prosecuting, Jonathan Savage, said:
'He was then struck a single blow to the left eye with an object.The court heard there was a dispute between the women and Mr Lloyd's group of friends as she attempted to get in a black cab.
'His next reaction was feeling that he has been hit in the eye and feeling a long object in front of his left eye, he had to pull it out.'
Police arrived to the scene and Omar was arrested in a room at the Mercure Hotel where her boyfriend had been staying.
Mr Lloyd was treated at Manchester Royal Infirmary and later the Manchester Eye Hospital for injuries to his left eye. He was left suffering with bruising, cuts and bleeding to the lower lid, cuts to the upper lid and a fracture to the eye orbit.
After the incident he spent 30 hours in hospital as his eye was stitched up, fearing he would lose his sight.
The court heard miraculously he did not lose his eyesight, but still suffers with stabbing pains and the psychological after effects. Since the attack he said he has lost his confidence and no longer wants to socialise with friends.
He told the court she was only brandishing the heel to stop Mr Lloyd hassling her friend, with no motive to actually strike him in the eye.
He said:
'She acted using excessive self defence, describing the group as intimidating very tall young men who were clearly aware of their level of intoxication.'Judge Lindsey Kushner QC sentenced Omar to 18 months imprisonment, suspended for two years.
Omar must also complete six months of unpaid community work and supervision, as well as pay a £100 victim surcharge fee.
