Icebug Acceleritas8 RB9X

RB9X is Icebug's proprietary sticky rubber compound used in the outsole of the Acceleritas8, offering exceptional grip on wet and slippery surfaces. Combined with a Vibram® MegaGrip layout, it provides runners with aggressive traction on challenging terrain. This makes the shoe highly effective for technical trail running and obstacle course racing.

Yes, the Icebug Acceleritas8 utilizes a protective rock plate embedded within the midsole to shield the runner's foot from jagged debris. This underfoot protection is crucial when navigating uneven terrain filled with sharp rocks and roots. It allows you to run with confidence on aggressive trails without worrying about foot bruising.

While the Icebug Acceleritas8 offers exceptional traction for wet conditions, its lug pattern is designed more for general stability and uneven trails rather than deep, thick mud. The Vibram® MegaGrip outsole excels on slick rocks and wet grass, but heavy mud can sometimes pack into the lugs. For deep mud, runners might look for a shoe with more aggressive, widely spaced lugs.

The shoe is highly favored by the obstacle course racing community due to its aggressive traction and unrestrictive upper design. The sticky RB9X rubber helps racers grip muddy walls, ropes, and wet terrain more effectively than standard trail shoes. Its overall durability ensures it can withstand the physical abuse of OCR events like Tough Mudder or Spartan Race.
