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 Sky LE

The SCARPA Alien Sky LE is a limited-edition trail running shoe engineered for vertical terrain and the most technical trails, where precision and responsiveness make the difference. Every component is purpose-built to keep you connected to the ground: agile, protected, and in complete control.

Progressive outsole system → ensures direct ground contact while absorbing impact progressively, so you stay stable and agile through every pace change
Vibram® Megagrip technology → delivers reliable traction on rock, mud, and extreme slopes, so you can commit fully regardless of conditions
Integrated gaiter upper → wraps and protects the foot while maintaining a direct connection to the ground, reducing debris intrusion and improving precision on technical terrain
Lightweight construction → keeps the shoe fast and unobtrusive underfoot, so your energy goes into the climb, not carrying the shoe
Limited Edition White/Tonic colorway → a premium, race-ready aesthetic that reflects the performance pedigree of the Alien line and stands out on the most demanding trails

Lightness, precision, and propulsion, the Alien Sky LE is built to help you overcome every limit on the trails that matter most.

*SCARPA North America suggests you consider ordering a half-size up from your normal running shoe size.
