Summary

Ultra Mini usually fits true to size as a whole-size Classic-family boot. New pairs feel snug until sheepskin packs out — between sizes, round down. Wide feet or thick socks may size up; do not size up just because day one feels firm. Partial vs Whooga snug/half-up notes.

Fit depth guide

Conditional: (1) Usual whole size → TTS and wait for pack-out. (2) Half-size wearer → round down so the boot does not turn sloppy. (3) Wide / thick socks → size up instead of forcing the smaller Classic habit.

Versus Tasman: opposite between-size habit (Tasman rounds up). Versus Classic Mini: same length logic, different ankle height/entry.
