Soar x Altra featuring RHEON™

Soar running, pioneers in high-performance apparel, and Altra, a trailblazer in running footwear, have joined forces to set a new benchmark in trail racing. Uniting Soar’s precision-built apparel with Altra’s trail-tested expertise, the collection delivers a complete racing system engineered for speed, protection, comfort and control.

The Soar x Altra capsule collection has been designed as a cohesive system to perform in unison on race day, in heat, over long-distance, and across rugged terrain.

Take it to the trails

Following our first link-up with Soar in March on the MARATHON SHORT, they are now  bringing the benefit of RHEON™ to the trails.

The TRAIL RACE SHORTS, a stripped-back half tight built around RHEON™ technology, adapting to the movement of the run, stiffening under force to absorb energy, then relaxing for freedom of movement. With a waistband-free construction and integrated storage throughout, these shorts are made for technical terrain, long days, and elite-level performance.

Traditionally, athletes relied on compression to control muscle movement, often at the expense of comfort. RHEON™ changes that.

By integrating highly strain-rate sensitive RHEON™ strips across major muscle groups, this technology absorbs non-productive energy, reducing muscle oscillation without increasing compression.

With every stride, up or down the trail, these strips adapt to stabilise muscles – helping runners maintain their most efficient pace for longer, without distraction or discomfort.

Real-race testing

Every element in the collection was tested by elite athletes and refined through real-world racing, at pace, under pressure, and at elevation. Together, they form a complete race-day system — balancing propulsion, protection, and packability. Built with adaptive smart materials, meticulous design, and groundbreaking construction
