Sobe Sale


A tri-level penthouse at Continuum on South Beach -- first listed for $25 million in '07, and then reduced to $14.95 million last October, just sold -- for $9.9 million. Cash. Buyer: Alex Birkenstock, a German bachelor. Seller: Howard Steinberg, a retired Wall Street lawyer who was general counsel to a Canadian bank and a Japanese securities firm.

There is talk that Birkenstock is a member of the famed footwear family. ''He's not the shoe guy,'' insists Khashy Eyn, a New York real estate broker who brought Birkenstock to the deal. ``He's a private hedge fund guy.''

According to a January '09 article in Footwear News, a fellow named Alex Birkenstock was with Birkenstock USA, but ''stepped away from the operational business.'' His two brothers ''still have active roles'' in the company, the weekly publication says.

Birkenstock the condo buyer declined to comment. Steinberg, 47, and wife Lilly, 36, who have four children ages 4 to 17, bought the 7,374 square-foot condo on the 40th floor for $7 million in June '03. Particulars: four bedrooms, private elevators, rooftop pool, high-tech audio-visual and spectacular views. Movie director Wes Craven shot scenes for the thriller Red Eye at the condo.

Steinberg's Manhattan condo near Ground Zero is also on the market -- for $5.97 million.

Players: Coldwell Banker's Jill Hertzberg and Jill Eber, and Jamie Goff of Douglas Elliman Florida, for Steinberg. R3 International Realty's Asher Abadi, along with Eyn and PhilipAskeroth of Platinum Properties in New York, for Birkenstock.

Eyn, who plans to open a Platinum office in South Beach this year, says the Continuum sale closed in 48 hours. ``I've never seen such a quick deal.''
