SOAR x Altra Trail Race Shorts

- Close-fitting half-tight design: may feel snug for some, so consider sizing up for comfort.
- Waistband-free for chafe resistance but highly supportive during dynamic movement.
✅ Pros
- Laser-cut ventilation: Maximum breathability for your hardest runs.
- Race storage system: Secure rear pocket fits gels, a key, or a phone.
- Integrated brief: Supportive, smooth, and chafe-free.
- Silicone grip hem: Keeps shorts locked in place on technical descents.
❌ Cons
- Minimalist storage: One rear pocket only—may not replace a running vest.
Our Verdict
Dialed in for race day, these shorts are what you’d reach for when every ounce matters. From vertical kilometers to hot 50Ks, they deliver elite comfort without the bulk.
I’m a huge fan of compression apparel and always run or bike with compression calf sleeves – minimizes muscle injury and soreness, especially on hills. Additionally, I also use compression shorts for workout or running or biking.
Style Meets Performance: Complete the Kit
Whether you’re charging up alpine peaks or flying down forested singletrack, this kit screams premium performance with unmistakable style – Altra’s signature foot-shaped trail legacy meets SOAR’s London-born finesse.
| Product | Style & Colorway | Distinctive Element | Collector Appeal |
| Trail Race Top | Prism (rainbow/white) | Mix of mesh & abrasion-resistant | High |
| Printed Run Cap | Prism (multi-color) | Reflective details, ultralight | High |
| Trail Race Shorts | Black w/ Prism detail | RHEON strips + cargo storage | High |
The Prism colorway is bold, yet race-refined—making both fashion and function statement on the trails.
Sizing & Fit Recommendations
- Consider sizing up, especially if you are in between sizes or prefer a more relaxed fit. The apparel is tailored for a European “race fit”—more streamlined than North American counterparts.
- Shorts are snug to pull on but designed to “disappear” during active use.
- The top is slightly more relaxed; many find the best fit by going up one size if you’re broader on the shoulders.
Should You Buy?
YES—if performance matters.
The SOAR x Altra Trail Collection isn’t just a style upgrade—it’s a serious performance weapon for trail runners pushing boundaries. While it’s not the most budget-friendly kit, it’s one of the most advanced we’ve tested for hot-weather racing and technical terrain.
Pair it with your Mont Blancs or Lone Peaks, and you’ll feel unstoppable on the mountain. My mentor and business partner from the Natural Running Center, Dr. Mark Cucuzzella has been testing the SOAR x Altra Mont Blanc Carbon on various surfaces that he runs ultras on. We will have his review here in the near future.
