The study involved 286 students from the University of Canterbury and 922 students at the University of Alberta, Canada.
The results of the study would probably have been different if they hadn't used only students.
Ms Boyce said she was a handbag and shoe lover, but not on the same scale of Filipina politician Imelda Marcos (1000 handbags and 3000 pairs of shoes) or Sex in the City's Carrie Bradshaw.
Worldwide the female shoe industry is enormous. In the United States alone, 886 million pairs were sold in 2008 compared with 144 million dresses, skirts, trousers, cotton shirts and blouses combined.
Angela Cleary took her shoe fanaticism to a new level and got a job at an inner-Auckland shoe store.
She estimates she owns more than 100 pairs of shoes and has spent some $8000 on her collection.
"I just really love shoes,'' she said.
One pair of shoes in particular were her favourite item.
"They're like these blue and white suede wedges and they're just like this most gorgeous cobalt blue, like this (Angela strokes a nearby pair of blue sneakers adoringly).
"They're amazing.''
She agreed with the research that some women's love of shoes stemmed from idealised images of women in the media.
"The women that are pictured in the media are like the perfect woman, and how many women would fall into that category? That's not necessarily attainable but shoes and handbags are. They can make you go from feeling bluh about how you look to feeling fabulous. That's why I buy so many shoes because I love the way I feel when I'm all dressed up.''
Shoe enthusiast Ayla Surtees has precisely 86 pairs in her collection.
"I just like how you can have all different shoes for all different outfits. I love my heels mostly, especially out-there high-heels, ones which are seven inches high and things like that.''
She was convinced of the benefits of "retail therapy''.
"If I'm ever stressed out or whatever, shopping always makes me feel better. It's just nice having new things, pretty much,'' she said.
