Standard pairs ship first. Custom-fit (Pre Order) pairs move into production after scan and fit confirmation.
Your scan turns foot shape, stance signals, and fit preferences into a readable body-line profile. Measurements are saved to your user page, so you can review your data before choosing Standard or Custom-fit (Pre Order).

Structure






The pain
Comfort is a system of contact points. ALTERLAB maps pressure, flexibility, ventilation, and stance support into one body-line balance structure.

Creates a smoother first contact so the body line stays more stable at landing.
Guides pressure through the midfoot instead of forcing support into one hard point.
Perforation density controls flex, ventilation, and hold across different movement zones.
Wide forefoot geometry leaves room for natural expansion through push-off.



Conclusion
Start with scan data, choose the right fit path, and complete a pair built around body-line balance.
