"It just leaves you with this empty feeling," said student Jan Kelger, 28, as he stood in a Berlin beer garden with the German flag draped over his shoulders. "I was just sure that we were going to go all the way to the final."
Fans in open-air viewing areas fell silent and stared in disbelief at giant video screens as one Italian goal was followed by a second in the final two minutes of extra time.
The late goals stopped dead the chants of "Deutschland Deutschland" and halted Germany's World Cup ride in its tracks.
"It feels like crap to lose like this but you can't say that they (Italy) didn't deserve to win. They had lots of chances," said Simon Raiser, a 32-year-old lecturer from Berlin.
Buoyed by a recent outburst of national pride, German fans had set out for Tuesday's match dressed in Ballack, Klose and Podolski shirts and decked out with the black-red-gold German flags worn like togas, emblazoned on hats and painted on faces.

In Dortmund, where the match was played, some 200,000 visitors swelled the local population. Despite the support, Germany could not emulate the "Miracle of Bern" in 1954 when they beat favourites Hungary to lift the World Cup.
"I am gutted. I am going to support whoever plays Italy in the finals. This is the worst night of my life," said tearful 21-year-old student, Daniela Trenker.
Germany exceeded expectations on the pitch and as host nation, presenting a welcoming side to the million foreign visitors who were lured to the country by the World Cup.
No one had expected Germany to get so far nor had they predicted such an outpouring of patriotic fervour from a country generally at pains to avoid overt displays of nationalism, making defeat all the more difficult to bear.
"We'll probably only take it in when we wake up in the morning," said Markus Algermissen, a 37-year-old civil servant.
