What Our Gearhead(R) Experts Are Saying: "These poles are a game-changer for long trail runs and mountain races. The Trail Shark grip locks in seamlessly with the mesh strap for efficient power transfer, and I can clip in or out without breaking stride. They're ridiculously light but still strong enough for aggressive climbs, and when folded, they tuck neatly into a running vest or pack." When speed meets endurance, the LEKI Ultratrail FX One Trekking Poles rise to the challenge. Designed for serious trail runners chasing efficiency and stability, these carbon poles combine featherweight performance with LEKI's cutting-edge grip technology. Each fixed-length pole weighs just over six ounces yet delivers unwavering strength through the 16mm HRC carbon construction-ideal for demanding training runs, steep climbs, and race-day efforts. At the core of this pole's performance is the innovative Trail Shark system, the first grip-strap interface built specifically for trail running. The streamlined grip features 30% less weight than traditional designs and pairs with the breathable Shark Frame Strap Mesh for unmatched control and energy transfer. The ergonomic nose on the lower grip provides additional hand positions for precision and stability on varied terrain. When not in use, the four-section foldable design collapses to as small as 33cm, making storage simple when transitioning between technical climbs and runnable descents. Complete with a carbide Trail Running Tip and compact Trail Basket, the Ultratrail FX One is purpose-built for the runner who treats the mountains like their training ground-and never stops chasing the next PR.
