Deckers' action outdoor brand Teva has launched its TevaSphere footwear collection, which claims to improve stability for athletes on rocky terrain.

The company said TevaSphere technology delivers a more natural point of impact, efficient transition and superior stability on varied terrain, with its spherical heel and pod-arch system.

The pod-arch system provides stability without restricting freedom of movement or adding weight to the shoe, it added. 

Teva teamed up with sports science and human performance institute P3 (Peak Performance Project) to create the outdoor cross-trainer. 

The collection, which includes TevaSphere Speed, TevaSphere Trail eVent, TevaSphere Trail and TevaSphere Trail Mid eVent for men and women, will be available from February 2013. Prices range from US$120 to $140. 

"The majority of consumers continue to land on their heels whether running or walking," said Chris Hillyer, innovation manager at Teva. "We felt compelled to create a technology that allows people to transition through their stride in a natural way without expecting the consumer to change."
