Things you don't want your trainers to be made out of: Fire. Landmines. Lego. Metal.
While you won't find any platinum, iron oxide or zinc in the latest Nike Air Max 93 range, metallic elements have been a key inspiration. The latest colourways are based around the hues of rare metals known as lanthanides, translating into burnt red, orewod brown, cool grey and platinum white tones.
Their foot-hugging construction is made from much more conventional combinations of soft leather suede and patterned synthetic leather, while the 93's unique neoprene tongue construction cocoons you from toe to ankle.
