New Discoveries
How to Easily Turn Any Shoes Into *Grounding/Earthing* Shoes 🌍🦶
If you regularly train hard, spend time under artificial lighting, or feel “wired but tired” at the end of the day, chances are you’re living disconnected from one of the most foundational health tools on the planet: the Earth itself.
Modern footwear, especially cushioned sneakers or boots with thick synthetic soles, blocks your body from making direct electrical contact with the ground. This cuts you off from the anti-inflammatory, circadian-balancing benefits of grounding (also called “earthing”) that our ancestors got simply by walking barefoot or wearing thin, leather-soled shoes.
The good news is that you don’t need to toss out your favorite kicks just to reconnect with the Earth. Earth Runners has made it incredibly simple to convert any thin-soled shoes into earthing shoes with a DIY kit called The Shoe Sync. The kit includes everything you need to turn your existing shoes into grounded footwear.
I recently used the kit to convert my VivoBarefoot boots into full-on grounding footwear—no engineering degree or cobbler skills required. With nothing more than a hammer, a bit of time, and a pair of shoes with a sole ½” thick or less, this kit gives you a direct line to the Earth’s electrons. And if you’re worried about functionality, Earth Runners uses real copper and conductive laces that hold up across dirt, rock, mud, and trails, even hiking for hours.
Once your shoes are grounded, you'll likely start to notice subtle but powerful shifts like better sleep, reduced joint pain, faster post-workout recovery, and even improved blood flow. That’s because grounding helps regulate cortisol rhythms and supports your body’s electrical balance, much like recharging your internal battery. If you’ve ever felt amazing after barefoot beach walks or mountain hikes, you know exactly what I’m talking about.
And if DIY isn’t your thing? Earth Runners also offers pre-grounded, minimalist sandals and fashionable-looking shoes designed with zero-drop soles and Vibram® traction that blend ancient wisdom with modern comfort, providing you with full proprioception and grounding without sacrificing your performance.
Earth Runners has also graciously offered to GIVE AWAY a pair of Earth Runners and a pair of their brand new iON SYNC Tolos grounding shoes to one lucky winner! Want to enter to win? Follow me on Instagram here for more details. The winner will be contacted by DM and posted to my stories on Monday, April 28th. Best of luck!

📢 This Week in Health & Performance: What the Latest Research Says 🚀
☕ Caffeine Tolerance May Kill Your Edge: A new study suggests that habitual caffeine users may blunt its performance-boosting effects. If you rely on caffeine for an athletic advantage, researchers recommend a 1–2 week taper before competition to reset sensitivity (study link).
🔋 Fatigue Fighters: NAD + CoQ10: For those struggling with chronic fatigue, there's growing evidence that NAD and Coenzyme Q10 may help restore energy levels and cellular function (study link).
🏋️ Longevity Boosters That Work: Fish oil, vitamin D, and resistance training continue to show science-backed benefits for healthy aging and vitality. This trio supports cardiovascular health, bone strength, and muscle preservation as we age (study link).
📌 Key Takeaway: Caffeine cycling could be the missing link in your performance prep, and don’t overlook the power of foundational nutrients and strength training for long-term health.

Product Of The Week
::: Save 20% on the Gut-Backed Probiotic That Cranks Up Your Metabolism 🔥 :::
Most people don’t realize this, but your metabolism actually begins in your gut. And there’s one bacterial strain that sits at the center of it all: Akkermansia muciniphila.
This keystone species plays a major role in sealing the gut lining, regulating blood sugar, and naturally boosting GLP-1—the same appetite-controlling hormone that’s now driving a billion-dollar drug market. The problem? Thanks to aging, stress, and the modern diet, most people are running dangerously low on Akkermansia.
That’s why I’m a big fan of Pendulum’s Metabolic Daily, the first and only clinically-backed probiotic that delivers live Akkermansia directly to your gut. This one-of-a-kind probiotic was developed by top researchers from institutions such as Johns Hopkins, Harvard, and Stanford. Here's what it does:
✅ Naturally boosts GLP-1 production*
✅ Supports metabolic flexibility and energy regulation
✅ Strengthens your gut lining*
✅ Reduces cravings and helps keep blood sugar steady
If you're serious about optimizing your gut, revving up your metabolism, and performing at your peak, this is a no-brainer.
*Based on preclinical studies.
