Before you buy — common questions.
The SD32 uses gentle warm air (105–140°F) combined with fan circulation to dry shoes evenly and quietly. It helps remove moisture quickly from sneakers, boots, or ski shoes without overheating. With dual power support (100–240V for home and 12V for car use), it’s designed for everyday convenience, travel, and outdoor use.
The SD32 is ideal for drying lightly damp shoes after daily wear or sports, including sneakers, boots, and ski shoes. If your shoes are soaked after washing, we recommend wringing out excess water before use for faster and more effective drying.
The 12V cigarette lighter socket is standard in most passenger vehicles, including sedans, SUVs, and MPVs. Please note that heavy-duty vehicles such as trucks and large buses typically use a 24V system and are not compatible with the 12V mode.
