God Save My Shoes, examines women's relationships to their footware.
If that's not enough to knock you off your six-inch stilettos, consider this: 700 of Shak's shoes are Christian Louboutins, the man behind one of her favorite pairs, $4,000-plus rose gold heels with spiky straps and Swarovski crystals that only she, Victoria Beckham and 10 other people own.
"Every time I wear them I have people who try to take them off my feet," she said with an impish smile.
And though the petite, girlish Shak looks nothing like superstar singer Beyonce, the two share the same taste in shoes: they both own French black lace Louboutins with gold Swarovski crystals.
Shak, 43, is standing in her former sitting room-turned-shoe closet which houses the cream of the crop: the Louboutins, the Steigers, the Blahniks, the YSLs. There are three other closets stuffed with older models or those of a lesser provinence.
Today, she is wearing scarlet suede strappy Louboutins to match a simple red dress, which serves to highlight the fabulous footwear. She spent the day with a film crew from the Today Show in her house and even dashed off to Saks Fifth Avenue so they could shoot her buying, what else? a pair of shoes.
Despite all the attention that comes with being a card shark and shoe hoarder, not to mention a one-time contestant on Bravo's The Millionaire Matchmaker, Shak considers herself "just of a mom of three kids who lives in Bryn Mawr" even if the kids tell her, rightly so, that she's not the average Main Line soccer mom.
Though Shak has loved shoes ever since she was a little girl, she began seriously collecting in her 20s and admits her shoe-buying binge was an easy, if expensive, pick-me-up during some rocky times in her life.
"I was filling a void in my life. It turned into love/obsession," said Shak, who grew up in Elkins Park and is divorced from an oil-futures trader who is a world class poker player himself. "Now I'm in a better place, I buy less."
But she still scores new shoes every time she competes in a poker tournament - next up is Cannes in October, if you are listening Christian - which may explain why she recently gave away about 200 pairs and is looking to donate a few hundred more to charity. Raise your hand if you're a size seven.
"You can only have so much of anything," said Shak, who also has an apartment conveniently located on Fifth Avenue in New York, a mecca for retail therapy.
She won't reveal her favorite designer - you can probably guess - but says YSLs are the most comfortable. She can't remember her first designer purchase and loses track of what she owns.
"Oh, I forgot about these," she said of a pair of black and green Jimmy Choos, as she looked through a third-floor closet of to-die-for shoes that she rarely visits anymore.
And while Shak never used to leave the house without balancing on heels, she now permits herself the occasional foray in Lanvin ballet flats and even... flip-flops.
Daher, a French businssman who produced the shoe movie - his second one about footware - called Shak "The Queen of Spades," referring to her pink patent six-inch heels with the black spade on the side custom-made by legendary shoe designer Walter Steiger.
The movie's director, Julie Benasra, said Shak was the most passionate collector she interviewed.
She "truly feels love for shoes, genuine love. Her eyes sparkle when she sees a pair she hasn't worn in a while or when she talks about how far she went to get that specific pair," she emailed from France, where she lives.
The film, which is expected to premiere during New Yorks' fashion week this fall, concludes that women's love of shoes is rooted in sexuality. They even get neurologists and psychologists to say as much on camera.
"Pretty much every single theory has to do with seduction and sex," Daher said. "Some will go so far as to say there's an analogy between the foot and the penis. But that's a Freudian thing. They see penises everywhere."
