Just how similar are an air-filled mountain bike tire and the flat sole of a shoe? Well, Adidas and Continental apparently believe that what works on one should also work on the other. To that end, the two companies have collaborated to produce the Terrex X-King – a trail-running shoe with mountain bike tire lugs providing the grip.

The shoe features the same tread pattern and rubber compounds as found in Continental's popular X-King tire. According to that company, the tire is designed to simultaneously maximize traction and durability, while minimizing rolling resistance. Adidas guarantees that the shoe will provide "ground penetration for grip at full speed."
