## Description

FITTING: The most important thing to remember when getting fitted out with your new straps is how well the strap adheres to the shoe will decide how long the strap lasts! If it isn't fitted properly, the strap will not last long as it will get beaten up by the terrain. 99% of all damaged straps come down to how the strap was originally fitted. PICKING THE RIGHT SPOT!: It is always best to find a spot on the shoe sole with a smooth flat surface. This ensures that water can't get between the adhesive and the shoe. It is also helpful to pick a spot on the sole which looks to wear out last. Finding a good spot like this can result in the strap remaining in great shape for the entire life of the shoe. PREPARATION: After picking the right spot, making sure the spot has been properly cleaned with water and completely dry with a cloth is also key! Once the area is clean, wiping the spot with the preparation sachet provided in the pack will ensure an industrial strength bond on any shoe type. STICKING: Keeping good pressure on the ce stuck for a few minutes will help activate the bond. Leaving the shoe for 24 hours after its stuck will complete the job and the strap will now be ready to go. TESTING THE STRAP: The best way to test the strap is a voltage reading with an electrical multi-meter. The material which causes grounding in the straps is a pressure sensitive carbon matrix which means that testing with a continuity tester can be tricky. Using a multi-meter and testing voltage differential is a sure-fire way to test grounding, rather than a common method of using continuity tests which test for continuity. A multi-meter can give a reading on the difference in voltage between the ground and the body which is the gold standard test as this differential can only occur if there is a path to ground.

Review: I've wear the shoes maximum of 10 days, I'm not really walking outside, I don't think I've walked more than 5 miles outdoors.

## Features

- MADE IN AUSTRALIA: With over 7 years of continuous research and development, the all new earthing strap has been developed with Australian Olympians and Elite Sports Athletes. Exclusively researched, developed and manufactured in Australia. The latest version has arrived and is in pre release, you may receive the latest generation strap with even more superior wearing, earthing and grounding strap from all new materials.
- PROBLEM: Your body naturally produces electricity to function. Any excess electrical energy that the body does not use is sent to the Earth when you are barefoot (known as grounding or earthing). Common footwear prevents grounding or earthing because it is insulating. This creating positive charge in your body. If not treated, it can lead to inflammation, poor sports performance, longer recovery times, increased muscle soreness and fatigue, elevated stress hormones and bad sleep.
- SOLUTION: The PRJ20(tm) strap solves the problem by making sure the wearer is always grounded when wearing any shoe. PRJ20 uses the latest nano particle technology which enables it to self-heal from wear. A better alternative to grounding shoes, grounding socks or grounding earthing mats because this grounding and earthing strap stays on your shoe all day long. Ground and Earth the footwear of your choice! You won’t even know it is there.
- GROUNDING AND EARTHING BENEFITS: Grounding and Earthing allows you to stop positive charge build up and makes sure your body can naturally keep inflammation under control and reduce stress hormones. This can reduce chronic pain, reduce muscle soreness, decrease sports recovery times, promote muscle recovery and improve the quality of your sleep.
- QUICK AND EASY TO PUT ON MONEY BACK GUARANTEE: Use this grounding/ earthing any work or sports shoe. The grounding strap is applied to the inside and outside of your shoe using the adhesive backing on the strap. Ground ANY shoe. Removes without damaging your shoe. Two Straps in this pack. Please refer to product description.

## Questions & Answers

**Q: Does it works even I use socks?**
A: Hi Jose,

Absolutely! Your sock will not prevent you from being grounded when using the strap.

Thank you

**Q: Are these easiely change-able from shoe to shoe? May I switch it to whatever shoes I'm wearing with ease?**
A: Hi, 

The straps are designed for single shoe use only and cannot be changed to another shoe. Once the shoe is prepared properly the straps will stay in place very firmly. 

Thank you

**Q: Do i need to wear 2 at the same time for maximum benefit ?**
A: Hi Andy,

Wearing two straps gives you the maximum benefit as your are constantly grounded. The chance of building any static or positive charge is completely eliminated by wearing two straps.

Thank you

**Q: Do these work on children's shoes?**
A: I’d think so. Just put them on over the back of the shoe (which I did, too) instead of the side so the longish strip can be stuck down the inside of the shoe.

I hate to leave a bad review and I really wanted to like these because I believe in the science behind them and don't want to spend hundreds on leather soled shoes but... after a week of normal use (I do hour long walks to the beach every day), the were both broken so I basically had to throw them out. I'm really only leaving this review here so that others can make an informed decision while shopping.
