Jane, 69, a retired seamstress from Sowery Bridge near Halifax, said she'd been saving up for a new pair, and that her big win meant she was able to buy them sooner rather than later.
"I usually get a pair from M&S because I love their slippers," she told the Daily Express.
"It was nice to buy a pair this year and not have to worry about the cost. They have gone up to £18, you know."
After her numbers came up, Jane got her son to double-check she'd actually won the quadruple rollover, and the two stayed up until 3am laughing with disbelief.
Jane said that she had an eerie sense of premonition that made her buy five extra tickets on top of her normal numbers that she played with every week.
"I've never bought a lucky dip ticket before and never played on a Wednesday, but I had this strange sense that I needed to buy this ticket," she said.
Jane admitted that buying the five £2 tickets was a big gamble, but it certainly paid off.
"I thought £10 out of your pension's a lot," she said.
Jane, who has five children and 11 grandchildren, is planning on moving into a house with a bigger kitchen, and also wants to make the ultimate Elvis fan's pilgrimage to Graceland.
