The [airflow](/source/Airflow) causes the shoes to dry faster. The air can be heated for even faster drying, and these are the most common types.[1] Shoe dryers can be especially useful for people who frequently have wet shoes, such as families with small children or for those who often hike outdoors, or for [ski boots](/source/Ski_boot) which are typically moist after use. Many shoes dryers have a timer which shuts off the dryer after awhile.[2] There are also shoe dryers which instead use a [heated grate](/source/Grate_heater) that the shoes are placed on top of, and also do not blow air. ## Noise Many fan-driven shoe dryers emit bothersome noise during use.[3] In a test from 2019, the most silent model was measured at 45 [decibel](/source/Decibel) (dB),[4] while the other models were measured at 50 and 57 dB. In 2022, another model was measured at 56 dB in "tornado" mode and 29 dB in "whisper" mode,[5] and in 2023, a different variant of the same dryer was measured at 72 dB.[6] It was also stated that the higher pitch of those models noise could contribute to it being perceived as more intense and bothersome.[6] ## Air flow The [volumetric flow rate](/source/Volumetric_flow_rate), i.e. the amount of air that is moved, is an important measure of fan-based shoe dryers. For example, a model tested in 2023 was said to have a volume flow of 12 [cubic meters](/source/Cubic_meters) per hour (m³/h), which corresponds to 12 000 liters per hour or just over 3 liters of air per second.[7] ## Heated air Shoe dryers with a fan often emit slightly tepid or warm air. In a test from 2019, one of the models was rated at a power of 350 [watt](/source/Watt),[4] of which 30 W was utilized as fan power and the remaining around 320 W were used for heating. Another model in the test had two temperature settings for choosing between 40 °C and 55 °C air temperature.[4] A model tested in 2023 had settings for blowing air at room temperature, or heated air at 37, 45 or 60 degrees Celsius.[5][6] Not all shoes can withstand heated drying.[8] Using high heat can put wear on shoes made of certain materials. For example, the use of a tumble dryer, heating cables or [heating cabinet](/source/Drying_cabinet) can lead to leather shoes cracking.[8] ## Fire hazard Shoe dryers with heating can be a fire hazard if left on for too long, as with any heating appliance, and should therefore be used under supervision.[3] ## See also - [Dehumidifier](/source/Dehumidifier) - [Drying cabinet](/source/Drying_cabinet) - [Drying room](/source/Drying_room) ## References 1. **[^](#cite_ref-1)** [The Best Boot Dryers for Damp Footwear - Bob Vila](https://www.bobvila.com/articles/best-boot-dryer/) 1. **[^](#cite_ref-2)** [Best i test 2019 - Test av skotørkere](https://dinside.dagbladet.no/bolig/test-av-skotorkere/71716108) 1. ^ [***a***](#cite_ref-klikk-1_3-0) [***b***](#cite_ref-klikk-1_3-1) [Test av skotørker - Tester og barneutstyr](https://www.klikk.no/foreldre/barn/tester-og-barneutstyr/test-av-skotorker-3686556) 1. ^ [***a***](#cite_ref-:0_4-0) [***b***](#cite_ref-:0_4-1) [***c***](#cite_ref-:0_4-2) ["Best i test 2019 - Test av skotørkere"](https://web.archive.org/web/20210123233747/https://dinside.dagbladet.no/bolig/test-av-skotorkere/71716108). 2021-01-23.
