Jarv RB9X Trail Running Shoe - Women's

What Our Gearhead® Experts Are Saying:

"I’ve put the Järv RB9X through long, technical runs, and it stays surprisingly comfortable. The bio-based midsole has great rebound, the upper holds the foot without squeezing, and the RB9X outsole grips when trails get unpredictable."

We pull on the Icebug Järv RB9X Trail Running Shoe when the trail ahead stretches for hours and the terrain won’t make it easy. Designed alongside dedicated trail runners, Järv brings a balance of cushioning, traction, and durability that helps us stay steady from the first climb to the last rocky descent. The woven engineered upper wraps the foot comfortably while leaving enough space in the toebox for natural movement as miles stack up.

When the ground turns slick or uneven, the RB9X outsole’s aggressive tread steps in to give us traction on mixed surfaces that don’t require studs. Its Susterra midsole—made largely from bio-based materials—keeps the ride cushioned and energetic while shifting away from virgin oil use. Whether we’re chasing big goals or discovering new routes, Järv RB9X delivers reliable support with a meaningful lean toward lower-impact design.
