And the perfect size, shared by renowned beauties Sopia Loren, Victoria Beckham, and Kim Kardashian and Sophia Loren, is best set off with three inch heels and red toe nail varnish, according to the study.
The research even concluded that nearly half of men will look at a woman's feet on a first date and a third will make a character judgement based on the state of them.
The poll of 2,000 adults, by foot plaster company Compeed, revealed six out of ten women admit to trying to hide their feet from other people because they are self-conscious.
One in five recalls feelings of embarrassment following a comment about their feet being unattractive.
The top foot related worry for women is cracked heels and dry skin, with 38 per cent, chipped nail varnish, 29 per cent, and blisters and corns, 14 per cent.
Compeed spokesman Niamh Finan said: “Men and women are becoming more judgemental of others based on the state of their feet.”
