Calibration Instructions
-
Anatomical Measurement: Stand on a level surface with your heel against a flat wall. Measure the straight-line distance from the wall to your furthest toe tip.
-
Matrix Mapping: Locate your exact linear measurement in the CM or Inch column, then reference left to determine your definitive purchasing size.
-
Dynamic Fit Note: The Neo-Mesh upper engineered for the Stealth Voyager '25 adapts directly to your foot posture. If your measurement lands exactly between increments, choose the lower size for a high-performance, locked-in compression fit, or the higher size for a versatile, casual silhouette.
1.Please select a suitable size depending on your foot length;
2.Once you know your foot length, consult the Size Chart to determine which size you should purchase.
