BW Infinity was one of Hi-Tec’s best running trainers back in 1989. A pioneering hybrid trail and road running shoe designed specially for the race in Badwater itself. A 146 mile ultra marathon from the dust plains of Badwater to the top of mount Whitney in the USA. The RGS tooling used was developed by Hi-Tec as a regular trail running tool in 2011. The density outsole on the tooling has been adapted to fit the streets.
