Danner Mountain Light II black boots
The black boots worn by James Bond (Daniel Craig) in Austria, in the Höffler Klink and the following action sequences with the airplane, are Danner Mountain Light II black boots.
The Danners are made in the USA, have a solid stitchdown construction, Vibram Kletterlift outsoles, and full-leather support. The Mountain Light II comes in two different widths: Men's D (medium) or EE (wide), make sure to get your right size if you order the boots online.
During filming of certain scenes, Craig used black anti-slip grips or ice cleats with steel spikes (the rubber with yellow circles and metal spikes) although those are not seen in the final film.
These are the same brand but different model boots that Craig wore at the photocall in Austria.
The boots are different from the ones worn by Bond in the Mr. White meeting scene. In that scene it looks like Bond wears black Crockett & Jones Northcote boots.
