Preface
HMSPACES Heating Shoes is an invisible electric heated shoes. The heel has a built-in safety lithium battery as heating shoes energy, and insoles are built-in high-quality electric heating wire, in order to make the shoes insoles to be safety and comfort, the electric heating wire is designed to be small, water-resistance, corrosion-resistance and anti-extrusion. The entire heating equipment is hidden inside of the shoes, so the shoes appearance is nice-looking. The sole uses a combination of new MD + RB material, which makes the shoes light weight and antiskid. With the equipped infrared remote control, you can turn on/off the heating function at any time.
The heating shoes are designed for all kinds of people to keep feet warm and prevent chilblain in cold weather. Meanwhile we conducted a variety of extreme product testing to ensure the safety of use.
Know what makes up the heated shoes
In understanding why we need to conduct a safety test on Hmspaces heated shoes, we consider that there has necessary for you to understand the approximate internal structure of the heated shoes. You can see that we make the heated shoes as simple as possible and directly combine the electric board with the battery to improve the safety of the heating circuit.

The hit testing for battery

We test this to make sure the shell of battery is strong enough against to the impacts from human body when walking, running.
There is a battery pack inside the heel of each shoe, in order to ensure the battery can withstand the impact of walking or jumping in daily use, we performed 10,000 hit testing for each battery back.
The pressure testing for battery

The heel is the most direct support for the weight of the human body, the battery and the circuit board are protected by the heel, generally it will not be subjected to very strong pressure, but just in case, we still designed the battery and the circuit board to be high strength against pressure, we must ensure it is not fatally damaged even in extreme environments.
There is a battery pack inside the heel of each shoe, in order to ensure the battery can withstand the pressure of body weight in daily use, we performed car pressure testing for each battery back.
The water-resistance testing

Inevitably, the shoes will be soaked when you are in heavy rain or when you wash your heated shoes, please be assured that the battery and circuit board and even the charging connector are waterproof designs.
The entire circuit is water-resistance design. The shoes can be washed and charged underwater. In order to ensure the safety of circuit, we performed a month of underwater testing for each circuit.
