Only use a method explicitly permitted by the footwear and appliance instructions. Loose footwear can create impacts, and materials such as adhesives or foam may have heat restrictions.
Understanding this situation
A drying rack or accessory is also model specific. Improvising a restraint or tying shoes to the door does not establish a safe approved arrangement.
A useful next step
Check both sets of guidance before use. If suitability is unclear, use the footwear's prescribed alternative. Stop a cycle through safe documented controls if heavy impacts occur, and do not assume the banging is harmless merely because shoes are inside.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
