RB9X®

RB9X® – Rubber 9 Extreme is our latest rubber compound development, and it sets a new standard in providing friction. Lab tests (SATRA) show that RB9X® outgrips the competition, but still matches the durability of an asphalt running shoe. In the real world, that means much more reliable traction in wet and slippery conditions and on challenging surfaces like rocks.

– RB9X is definitely a benefit for extremely demanding runners with high expectations on the shoes traction in mixed and tough terrain. RB9X is a new compound and tests show that we really have succeeded. There’s nothing like this on the market, says Erik Öhlund, member of the Product development team at Icebug and an elite orienteerer.
