We combine thoughtful engineering with refined aesthetics to deliver efficient, quiet, and reliable products.

Q1: What about after-sales support?
Sothing Ultra comes with 12 months of reliable after-sales support for peace of mind. If you have any issues, please tell us anytime via ’s ‘Contact Seller’ feature, and we will respond ASAP.
Q2: How long does it take to dry boots or shoes?
The Sothing Ultra offers a 1–9 hour timer for flexible drying cycles. Drying time depends on the material and moisture level—light trainers dry faster than heavy boots or ski boots.
Q3: How do I use the ozone function?
Press the Ozone button and set the timer (1–9H). The built-in ozone generator works with the fan to blow ozone through the hoses for deodorizing and sanitizing. The output is 5mg/h, a low concentration that is safe and usually undetectable to human senses.
Q4: Can ozone and drying work simultaneously?
No. Heat and ozone run separately. Ozone decomposes at high temperatures and loses its deodorizing effect, so to ensure the ozone function works effectively, the Sothing Ultra is designed so that drying (heat) and ozone modes cannot be used at the same time.
Q5: Is the temperature adjustable?
Yes. The boot dryer has three heat levels (~113°F–149°F). Use low for delicate shoes, medium for sneakers, and high for rugged boots.
Q6: Does it have overheat protection or an auto shut-off feature?
Yes. The dryer is equipped with triple safety protection. The PTC heating chip will automatically cut off power if the temperature exceeds safe limits and resume once it cools down. It also includes a built-in thermal fuse as a backup safeguard, and the exterior uses heat-resistant housing to ensure safe, reliable operation during every use.
Q7: Does it have a timer function?
Yes. Set 1–9 hours for automatic shut-off. Works with both heat and ozone modes.
Q8: Is it safe to leave running overnight?
Yes. The timer, auto shut-off, and overheat protection make overnight use safe.
Q9: Does it have extendable or foldable hoses for different shoe sizes?
Yes. The air hoses are retractable, extending up to 11.8 inches, fitting sneakers, work boots, and ski boots comfortably.
