Birkenstock has set a price for its initial public offering of stock that values the 249-year-old German maker of upmarket sandals at $8.64 billion.

The company said Tuesday that it had priced its IPO at $46 a share, in the middle of its expected price range of $44 to $49 per share. It is due to start trading Wednesday on the New York Stock Exchange under the “BIRK” ticker symbol.

The company’s footwear was first cobbled together by Johann Adam Birkenstock in Germany in 1774. The sandals have long been derided as the antithesis of high fashion but have a cult following and this year got a plug in the blockbuster film “Barbie.”
