Adidas Gazelle 2

In the workout scenes in SkyFall (2012), James Bond (Daniel Craig) wears a pair of blue Adidas Gazelle 2 sneakers. These iconic Adidas Gazelle II sneakers are available in many colours, and in leather or suede. The version worn by Bond is from the Spring 2011 collection, Adidas Gazelle 2 Dark Indigo with Argentina Blue stripes and White soles, suede upper on rubber soles, as pictured on the left, except that the heel part is also black in the movie. If the heel was made black by the costume department or a specific model is unknown. During rehearsels for SkyFall, Craig does wear shoes with the blue heel as pictured on the left.

Bond is dressed in an all blue outfit, with a blue shirt with SIS logo, blue jogging trousers, and a blue Puma training jacket. Much of the fitness measurement equipment used in those scenes was provided by Cosmed.

The Gazelle is of the most iconic Adidas trainers ever produced: simple, soccer inspired. Originally released in 1968 as an all-around sneaker, the Gazelle soon became an international sneaker icon. 

The exact same sneakers as seen in the film are hard to find. You can try eBay or your local sports shoe stores. By the way, don't buy the sneakers on  www . trainersadidas . co.uk, which is an unofficial and untrusted website.

Alternative
Adidas still has the Gazelle in their collection, but currently (updated October 2021) with white tongue, white stripes and gold Gazelle text, get these on Amazon UK (£55) or at Farfetch for $70.

Complete the outfit
You can get a replica SIS Training Gear shirt from an unofficial fan site (not related to the real SIS). They offer a great selection of shirts and trousers with the SIS logo, very close to the one seen in the movie.
