L.L. Bean hired 100 new employees and added a night shift to meet the shortage of its famous duck boots. The company has a wait list of 100,000 orders for the boots.

While many people were hoping to buy the iconic L.L. Bean duck boots as Christmas gifts, L. L. Bean is already completely sold out of the boots in women's size 8 with a severe shortage of all other men's and women's sizes, according to Yahoo! Style.

It's unlikely anyone will be able to get their hands on the boots until January or February at the earliest, Bustle reports.

L.L. Bean spokesperson Carolyn Beem told Boston.com that the company expects to sell about 450,000 pairs of the popular style this season, possibly due to their increasing popularity amongst the younger generation.

"Younger people are buying them. They're all over college campuses and high schools," Beem told Boston.com. "Without changing anything, they're back in style."

NPR reports L.L Bean has upgraded its manufacturing equipment and added a third shift at its Maine boot factories to meet the demand. Manager Royce Haines told NPR that L.L. Bean hired 100 new employees and added a night shift.

Part of the reason it'll take some time to catch up to the wait list is each boot is made in Maine, by hand.

There's "a lot of demand out there; back orders are building on us; the pressure is on. We've got some boots to make," Haines says

Some of the demand is driven by new fashion trends like "lumberjack chic," but L.L. Bean spokesman Mac McKeever said the boots have a broader appeal.

"These boots have always been popular with outdoorsmen - traditional outdoorsmen - and hunters and loggers and farmers, but they've seemed to garner favor in the fashion industry as well as with young folks, college campuses, folks from the cities. Obviously it's a welcome surge in popularity for us," he said.

"Everyone's doing the whole wool-sock-out-of-the-Bean-boot thing, whether it's with jeans or leggings," said Hannah Perkins, a Mainer who has been wearing the boots for years. She said they are now very popular with her classmates at Susquehanna University.
