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.

Helix Men's

For climbers who value all-day comfort and reliable performance on gym walls or long days outside, the new Helix offers a refined, supportive fit built for progression and enjoyment. Its relaxed, low-profile design keeps the foot in a natural position, reducing fatigue while practicing technique or moving across moderate terrain. The updated metal free suede upper molds smoothly to the foot without excessive stretch, creating a dependable fit as the shoe breaks in. A secure lace-up closure allows precise adjustments from toe to ankle, essential for multi-pitch routes or long training sessions. Underfoot, the Vibram® XS Edge outsole provides confidence-inspiring stability on small footholds, while the supportive midsole delivers balanced edging power without sacrificing comfort.


Durable, intuitive, and ready for full days on rock, the Helix helps climbers move with ease and certainty.


  • Suede upper molds comfortably to the foot while maintaining long-term durability.
  • Lace-up closure provides fine-tuned adjustment and secure support for long routes and varied terrain.
  • Vibram® XS Edge outsole offers reliable stability and edging support on gym holds and outdoor rock.
  • Supportive midsole balances comfort and precision for confident foot placements.
  • Relaxed, nearly flat last reduces foot strain and supports climbers on long sessions and moderate routes.


Refreshed for 2026, the Helix continues to be the epiphany of classic comfort and all-day reliability for climbers exploring more terrain.
