I bought two pairs for my parents before and learned a lot. After many comparisons, I still think that Shenzhen Huayang rechargeable warm shoes have the best technology and good quality and style. 1. Know its heating temperature. The heating temperature of charging warm shoes is above 39℃, because the heating temperature must be higher than the normal body temperature (note: the normal body temperature is 36.3℃-37.2℃), otherwise the heating shoes will not feel warm when worn on the feet, especially in cold winter (the heating temperatures of some heating shoes in the market are only 20℃-25℃, 25℃-45℃ and 25℃-45℃). 2. Know whether the fever time is lasting and stable. (At present, the heating time of some heating shoes on the market is only 3-8 hours, 4-6 hours and 6- 15 hours). Generally, the heating time is short and fluctuates greatly (for example, it is very inconvenient to wear heating shoes for a long trip or work outside for a day, and there is no electricity before you get home), so the heating time of constant temperature heating shoes is at least 65438+. After-sales service is also very important. Heating shoes are not a pair of ordinary leather shoes. In addition to the "three guarantees of quality" of conventional leather shoes, the electronic components of heating shoes should be guaranteed for at least one year. Otherwise, the shoes are not broken, but the heating system is broken. Will consumers lose?

Please accept it, thank you!
