Giant steps are what you take...

So goes the lyrics of the song "walking on the moon" by the police...

Have a look at the boots Spota is wearing in the zero gravity cell

Those are moon boots, with deep, wide tracks as the moons surface can be loose and dusty in places...

But IO is made of a lot sterner stuff, hard rock basalt and molten lava and would probably need something closer to golf shoes, with spike coming out the bottom..

What's that? These boots are just for the Zero Gravity cell, an interesting notion, but from everything seen so far costs are kept to a absolute minimum

No, its another nice stylistic choice by Steranko - maybe I need to get a grip :-)
