How to Measure Your Foot

Step 1Place a sheet of paper on a hard floor against a wall. Stand on it with your heel lightly touching the wall.

Step 2Mark the tip of your longest toe and the outermost point of your heel. Repeat with the other foot.

Step 3Measure the distance between the marks for both feet, add 0.5 cm for room, then match it to the chart.

For the most accurate result, measure your feet at the end of the day when they are naturally slightly swollen. If your two feet differ, use the longer foot when reading the chart.

Alien Ultra LE

The SCARPA Alien Ultra LE is a limited-edition trail running shoe built for athletes who are ready to go beyond their limits, turning every stride into pure forward motion. Every component is purpose-built to convert effort into speed, from the first stride to the final push.

Pebax + Carbon Plate midsole → continuously absorbs and releases energy, delivering explosive propulsion and dynamic response so every footstrike translates directly into speed
Vibram® Megagrip outsole → ensures reliable, smooth traction on any terrain — wet or dry — so you can push harder without hesitation
Second-skin upper construction → wraps the foot with precision and lightness, blending propulsion and stability into an adaptive fit that eliminates slippage and reduces fatigue over long efforts
Lightweight Pebax foam platform → provides targeted support where it's needed most while allowing complete freedom of motion without compromising control
Limited Edition White/Tonic colorway → a premium, race-ready aesthetic that reflects the performance pedigree of the Alien line

Lightweight, reactive, and engineered for maximum efficiency, the Alien Ultra LE is designed for fast running and the athletes who refuse to slow down.
