Wet shoes need a sequence, not a guess.
Drain free water, open the pair, read the care label and only then decide whether heated airflow belongs in the routine.
Direct answer
Remove standing water and open the shoe first. Take out removable parts only when permitted. If the exact footwear allows heated drying, keep airflow unobstructed and check progress; otherwise use the non-heated method required by the manufacturer.

When this applies.
This guide covers ordinarily damp shoes after rain, sweat or cleaning performed according to the shoe instructions. It does not establish heat compatibility for leather, membranes, glued constructions, custom insoles or any other material by appearance alone.
If the label is missing or unclear, stop before adding heat and ask the footwear manufacturer.
Work through the pair, not around it.

Tip out free water and blot the exterior using the method allowed for the material. Do not place a powered device in standing water or on a wet surface.

Loosen laces and open the tongue. Remove a footbed only when its instructions permit removal and it can be returned correctly.

If the label allows heated drying, follow the exact dryer placement and keep every inlet and outlet clear. If it prohibits heat, use the required non-heated method.

Inspect progress rather than relying on elapsed time alone. Switch off, unplug and let the unit cool as directed before storage.
Common mistakes to avoid.
Applying heat to standing water
Drain and blot first; a powered device never belongs in pooled water or on a wet surface.
Treating every wet shoe alike
Upper, membrane, adhesive, lining and footbed instructions can differ even when two pairs look similar.
Blocking the airflow path
Forcing an outlet into a closed shoe can change the documented setup and restrict airflow.
Trusting a fixed number of hours
Moisture level, construction and room conditions vary; inspect the pair before the next wear.
Where Zero Timing fits.
The current Zero catalog documents a one-pair warm-air routine and a named Timing option. That makes it a simpler product connection when the exact shoe permits heated drying and no Ultra kit attachment is needed.
The timer controls a session; it does not prove compatibility or guarantee a dry result.

Product price, option name and Shopify-context availability are dynamic. Material suitability, cleaning method and actual drying time still follow the footwear and product instructions.
