Acceleritas8 RB9X

Light as a bird – grip like a tractor

All good runs start with a good grip. Take a closer look at Icebug's model Acceleritas8 RB9X and you will discover that the sole has the same pattern as a tractor tire, a machine that can plow through anything. The result is the feeling of total freedom and fun running; it’s an unbeatable experience.

Low weight, low drop, and maximum grip are the hallmarks of Acceleritas. It's our lightest trail shoe, made for minimalist trail running and the feeling of almost running barefoot. Or, as close to barefoot as you can get in a trail shoe with protection against wetness and sharp stones on the surface.

This is freedom packed in a running shoe, made for you who love to have full control over the surface. The RB9X sole provides a good grip even on wet surfaces. The lightweight upper absorbs minimal water – a decisive factor for a shoe designed to perform well in all the elements of nature. The shoe's wet weight is almost as low as its dry weight.

These days, the Acceleritas8 RB9X also has a slightly wider toe box to provide comfort to a more diverse range of feet. A nicer fit with just as good performance.

How Acceleritas came about

Product developer Erik Öhlund was at home on his farm, and the tires on a tractor suddenly caught his eye.

It all started in a field outside Ulricehamn, Sweden

It was the spring of 2010. Our former product developer and orientator Erik Öhlund was at home on his farm outside Ulricehamn and started contemplating the tires on the tractor.

Here was a machine that could plow through mud, both uphill and downhill.

Suddenly a thought appeared. ''Why not develop a sole that can do the same thing?'' 

He returned to his workshop and began to work. The rest is Acceleritas history. A unique and fun trail shoe that has been loved by many.
