The LEKI Ultratrail FX.One is a four-section folding carbon trail running pole designed for runners who want a capable, lightweight pole across the full range of trail and mountain terrain. Carbon (HRC max) sections give it a stiff, responsive feel and a weight of 167 g per pole at 120 cm — meaningfully lighter than its aluminium equivalent and noticeably lighter than the previous generation of this model. The 37 cm pack size sits cleanly in a vest pole pocket, and the Push-Button folding mechanism collapses the pole at the press of a button without releasing the grip.
The Trail Trigger Shark grip carries a foam contact surface and integrates the Trigger Shark strap-release interface directly into the grip body. Pressing the button allows the Shark Frame Strap Mesh to click free from the grip instantly, leaving the strap on the wrist while the poles are stowed or carried. For runners who regularly transition between using and carrying poles, this is one of the most practical strap systems available.
The Ultratrail FX.One is available in six fixed lengths from 110 to 135 cm in 5 cm steps. Selecting the correct length at purchase is important as there is no adjustment mechanism. All four folding sections are individually replaceable as spare parts — a significant practical advantage for race and training use, where section damage is a realistic risk.
What’s new for SS26: Updated White/Stone graphics with tonal strap in Warm Grey Light / Warm Grey Dark / Black. The grip extender present on the SS25 model has been removed. Weight has been reduced — 167 g at 120 cm versus 182–190 g on the SS25 generation. All folding sections are now individually replaceable as spare parts. The Trail Shark grip of SS25 has been replaced by the Trail Trigger Shark, adding the click-in/click-out Trigger interface. The other colourway is available as the Ultratrail FX.One (LE65625851).

S+W Verdict:
"Top of the range running/walking poles from Leki. Ultra-light weight and super stiff, perfect for hike and fly. The trail shark is no gimmick, makes going uphill so efficient as you don't actually have to grip the pole! No wonder so many x-alps pilots use these..."
