Mission Impossible: How Is Tom Cruise as Tall as Cameron Diaz in Heels?

Just how is 5-foot-7 actor Tom Cruise able to stand as tall as 5-foot-9 co-star Cameron Diaz — who was wearing four-inch heels? That’s a six-inch difference if you are counting and our friends at StyleList break down just how they were able to orchestrate it at the Tokyo premiere of their film ‘Knight & Day.’

Standing side-by-side, Cruise and Diaz, who was poured into a belted black dress by Bottega Veneta paired with multicolored Jimmy Choo heels, practically matched each other inch for inch, as reported first in the Daily Mail.

Was this from a sudden growth spurt on Cruise’s side? A shrinking Cameron?

Neither, it turns out. The Daily Mail reports that Cruise may have reached new heights with the help of shoe lifts, special inserts placed inside a man’s shoe to raise his heel and make him taller.

The Daily Mail reports that a single pair of the tootsie transformers costs between £50 and £100 (that’s $79 and $159 U.S.), while a bespoke pair could set a guy like Cruise back a whopping £1,700 ($2,700 U.S.).

Pricey to be sure, but it’s not like Cruise can’t afford it and use the height boosters again: He’s currently filming “Mission: Impossible 4,” co-starring 6-foot-1 1/2 Josh Holloway and 5-foot-10 Jeremy Renner, who will no doubt find working with Cruise to be an uplifting experience.

‘Knight and Day’ was considered a box office disappointment here in the US, only reaching grosses of $76 million. But the action comedy has played better overseas, grossing over $150 million and certainly the A-list duo hopes that a successful run in Japan helps their rep as bankable worldwide stars. [Popeater]
