Miller, the defending overall World Cup champion, finished 29th and was more than two seconds behind leader Jean-Baptiste Grange of France before the International Ski Federation pulled him out of the competition.
"His boots were 0.2 millimeters too high, that's it," said Forest Carey, the head coach of Miller's independent ski team.
"It's black and white, the rules are clear so nothing we can do about that."
Miller's boots were tested in a random routine check by FIS officials that usually takes place between runs. FIS rules limit the height of ski boots to 34.3 millimeters because knee injuries often occur when boot soles are higher. Miller's boots were 34.5mm.
"Bode switched boots this morning, he got a new pair," Carey said.
"He is very disappointed that he can't race the second run. It's a night race, lot's of people out there, so he was fired up."
Carey said Miller was not aware he was racing in illegal boots and did not intend to cheat.
"Of course not," Carey said.
"Bode has been tested 380 times in his career so no way he would take any risks."
Miller is expected to stick with the boots, albeit with a slight adjustment.
"For the guy from (equipment supplier) Head it's a matter of five minutes to adjust the height," Carey said.
"I won't blame anyone in our team in public, but we'll have some words tonight for sure."
In December 2005, Miller was fined 999 Swiss Francs ($NZ1610) for refusing to hand over his ski boots for the regular FIS inspection after the opening leg of World Cup slalom in Kranjska Gora, Slovenia.
Miller had missed out on qualification for the second run then.
