Sizing, measured before it's promised.

Fit guidance depends on prototype and last data that is not yet finalized. We will not publish sizing claims ahead of that evidence.

Fit record

What is confirmed about fit today.

We separate what is currently documented from historical planning context and from steps that remain planned and unverified.

Historical Report

Early last concepts have been referenced in planning materials. They are not confirmed as final and remain subject to prototype review.

Planned-Unverified

An intended range of sizes is under discussion, pending prototype fit testing and approved size records.

Planned-Unverified

No comfort or break-in claim is made until supported by documented wear-test evidence.

Planned-Unverified

Any width or volume variants depend on component and last approval that has not yet occurred.

Path to publication

Historical Report
Concept sketches
Early fit and last concepts were discussed and sketched during initial planning.
Planned-Unverified
Prototype fitting
Physical prototypes will be evaluated against fit criteria before any sizing claim is made.
Planned-Unverified
Wear testing
A structured wear-test process is intended to validate comfort and durability under real use.
Planned-Unverified
Size-chart publication
A size chart will be published only after fit data is reviewed and approved.

Planned-Unverified

We will add sizing information here only after it is supported by approved fit and wear-test records.

FAQ

Can I get sized for Bertsi boots now?+

No. Fit and sizing guidance is not yet published. This page will be updated once prototype fit testing is complete.

Will Bertsi run true to standard sizing?+

This has not been determined. Any statement about sizing accuracy will follow documented fit testing, not assumption.

How will fit data be validated?+

Through a structured prototype and wear-test process, with results reviewed before publication.

Where will the size chart appear?+

On this page and on individual product records once approved.
