A timer controls a session. It does not promise a result.
Drying time changes with starting moisture, construction, airflow, room conditions and the permitted setting.
Direct answer
Use the timer as a checkpoint. Select only a duration and setting permitted by the product and footwear instructions, inspect progress, and continue only when appropriate.
When this applies.
This guide applies to products with a documented timer option. Current source material documents a 1–9-hour timer for Ultra and 3 / 6 / 9-hour timers for Lang and Zero Pro Go. Zero and Zero Pro have Timing-named catalog variants.
A control range is not a claim that every shoe will dry within that range.

Distinguish light dampness from free water. Drain and blot first where the footwear instructions require it.

Use the product manual and footwear guidance for the exact model and material. A lower setting is not automatic permission.

Treat the selected duration as the next time to inspect the lining, upper and footbed rather than as a guaranteed completion time.

Switch off as instructed, allow any required shutdown to finish, unplug and cool the unit before cleaning or storage.
Common mistakes to avoid.
Publishing one universal drying time
Starting moisture, construction, airflow and room conditions vary too much for one responsible promise.
Equating timer length with material safety
A short duration can still be unsuitable when the footwear prohibits heated drying.
Assuming every model has the same controls
Timer ranges and option names differ across Ultra, Lang, Zero, Zero Pro and Zero Pro Go.
Packing immediately after a session
Switch off, unplug and cool the product and accessories before storage.
Ultra as the control example.
Current approved Ultra source material documents three heat modes and a 1–9-hour timer. The interface is useful for explaining session control, but the valid setting and actual result still depend on the footwear and environment.

Control ranges come from current approved product sources and catalog copy. No fixed drying-time or unattended-use promise is made.
