Grounding Shoes Test by Multimeter: Measure Your Body Voltage Before & After

In our article “How to Properly Test Conductivity Whether Grounding Shoes Really Work,” we explained how to test the conductivity of grounding shoes using professional equipment. But if you only have a regular household multimeter, a simpler and more practical method is to measure your body voltage before and after wearing the grounding shoes.

For everyday users, body-voltage testing is often the easiest way to see whether the shoes are actually creating a connection to ground.

If your body voltage drops significantly when you put on the grounding shoes, it shows that a conductive path has been established between your body and ground.

Step 1: Prepare the tools
You’ll need:

• A multimeter that can measure AC voltage (V~), preferably with a millivolt range
• A reliable ground point, such as a properly grounded outlet or an outdoor grounding rod
• A conductive test surface

For indoor testing, a grounded outlet connected to a grounding mat is usually the easiest setup.

Step 2: Set the Multimeter

Set the meter to:

AC Voltage / V~

Connect the black probe to the verified ground point.

Hold the metal part of the red probe in your hand.

Step 3: Measure Your Body Voltage Without Grounding

First, wear normal shoes and stand on an insulating surface.

Hold the red probe and wait a few seconds for the reading to stabilize.

For example, the meter may show:

34 V

This is the AC voltage your body is picking up relative to the ground reference from the surrounding electrical environment.

The reading can vary greatly depending on nearby wiring, computers, chargers, lights, and other electrical equipment.

Step 4: Put on the Grounding Shoes and Measure

Now put on the grounding shoes and keep the same testing position.

One important point: the shoes must stand on a surface that is electrically connected to ground. In this test, I’m standing on a grounding mat connected to a properly grounded outlet.

Keep holding the red probe and watch the multimeter.

The reading drops from 34.6V to 1.2V — a 96.5% reduction in body voltage, showing a very effective grounding connection.

This confirms that the shoes have established a clear conductive path between your body and ground.

When testing, focus on the percentage drop before and after grounding, rather than expecting everyone to reach the same voltage reading.

3. Do an A/B Comparison

For an even clearer test, switch back to normal shoes.

Keep everything else exactly the same:

• Same location
• Same grounding point
• Same multimeter
• Same body position

For example:

Normal shoes: 6.8V
Grounding shoes: 0.4V
Normal shoes again: 6.5V

This makes the result much easier to understand.

The voltage rises with normal shoes, drops with grounding shoes, and rises again when you switch back.

That shows the grounding shoes are changing the electrical connection between your body and ground.

Why Doesn’t My Body Voltage Drop All the Way to 0V?

That is completely normal.

Body-voltage readings are affected by many factors, including:

• Nearby electrical wiring
• Computers and chargers
• Lighting
• Electrical equipment
• Ground quality
• Meter input characteristics
• Skin contact with the shoe
• The surrounding electrical field

So effective grounding does not mean the meter must show exactly 0.000V.

What you should look for is a large, stable, and repeatable drop in body voltage.

The Simple Test Logic

Normal shoes → Higher body voltage
↓
Grounding shoes + grounded surface
↓
Body voltage drops significantly
↓
Switch back to normal shoes
↓
Body voltage rises again

For most consumers, this is one of the simplest and most convincing ways to verify that grounding shoes are actually providing an electrical connection to ground.

Important: A reduction in body voltage confirms the electrical grounding function of the shoes. It does not by itself prove any specific medical or health benefit.
