Jessica Miller
The throbbing at night was so bad I'd hang my foot off the edge of the bed just to sleep. I wear this 15 minutes before bed and by week 2 the joint wasn't screaming anymore, I even got my regular shoes back on without wincing!
Who is it for?
Bunions (hallux valgus)
Big toe joint pain & pressure
Red, swollen bunion bump
Big toe drifting toward the others
Pain in tight or narrow shoes
Nighttime throbbing & poor sleep
Runners, walkers & on-your-feet days
Early bunions you want to slow
How to use?
EMS Muscle TrainingTrains the muscle
Wrap the device around your forefoot and fasten the
strap—snug but comfortable.
Slip the soft loop around your big toe so it is guided
into a straighter line.
Power on and raise the EMS until you feel a
gentle tingling contraction—never painful.
Relax for 15 minutes, hands free, while it
activates the abductor hallucis.
Alignment FrameRealigns the toe
The built-in frame holds your big toe toward its natural
line for the entire session.
This helps lift pressure off the swollen joint so it can
calm down.
It works at the same time as the EMS—
hold the toe and train the muscle together.
Best time to fit your 15 minutes
Morning15 min
Ease overnight stiffness and start the day loose.
After your day15 min
Relieve pressure built up from being on your feet.
Before bed15 min
Calm the throbbing so you can rest more comfortably.
Once a day is all it takes—pick the moment that fits your routine.
Tips for best results
Pressure may ease during the first sessions, while
muscle strengthening develops gradually
with consistent use.
Start the EMS low and increase it to a comfortable
tingle. Stronger is not necessarily better.
Fasten the strap firmly, but never tightly enough to
cause throbbing or numbness.
Consistency beats intensity—use it for 15 minutes
each day.
Tight shoes, daily pressure, and muscle imbalance can gradually pull your
big toe out of line, causing swelling and pain with every step.
But the problem isn't only the joint.
The abductor hallucis is the small muscle that helps hold
your big toe straight. When it becomes weak, the toe can continue drifting
toward the others.
Kadvio combines a gentle alignment frame with EMS microcurrents
to guide the toe, reduce joint pressure, and activate the supporting muscle.
One simple, 15-minute daily session helps support better alignment and
lasting comfort.

Fix your bunion at the source
Bunion surgery can run $5,000+, means weeks off your feet and the recovery scares most people off for years. So they reach for the cheap stuff, silicone spacers and rigid night splints, and hit the same wall every time.
The moment they come off, the toe drifts back, because a held toe is not a trained toe. Passive support can even let the muscle waste further.
This frame delivers the mechanical alignment that eases pressure and gives the joint room to breathe. The EMS delivers the active muscle work. In studies, stimulating the abductor hallucis measurably improved its strength and helped straighten the toe during movement — the exact muscle that keeps your big toe in line.
Teaches your toe to hold itself straight
Every night splint and toe spacer has the same flaw: the second you remove it, nothing is holding your toe but the same weak muscle that let it drift in the first place.
Kadvio's EMS retrains that muscle to do the holding itself. Repeated contractions rebuild the nerve-to-muscle connection and strengthen the abductor hallucis,
so it switches back on during everyday standing and walking, keeping tension on your big toe long after the device is off.

I'd basically accepted that bunions had ended my running.
I wore this 15 minutes a night and by 3 weeks in the sharp
pain at my toe joint eased off — I got through a long run without changing my stride.
I'm not hiding my feet anymore either.

01
First Use
Pressure Lifts
Slip it on for 15 minutes and the alignment frame gently
guides your big toe off the inflamed joint while EMS
microcurrents start firing the muscle around it. Most people
feel that hot, throbbing pressure ease in the very first
session.
02
Week 1–2
Swelling Settles
The angry redness and swelling around the joint calm down.
Each step lands softer, your regular shoes stop fighting you,
and the deep 1 a.m. throbbing quiets—so you can finally sleep
through the night.
03
Week 3–4
The Muscle
Wakes Up
The abductor hallucis—the muscle that holds your big toe
straight—starts switching back on. As it strengthens, the toe
sits straighter, stiffness eases, and the correction begins
to hold on its own.
04
Week 5–9
Back to Feeling
Like You
A few minutes a day keeps the muscle strong and the toe
aligned. Flare-ups become rare instead of running your day,
and the shoes you had given up on are back in rotation.
A 15-minute session helps keep the supporting muscle active and
pressure off the joint.
Your toe keeps its line. Every day.
Designed & backed by clinical research
The newest version of the Kadvio Bunion Device has been thoroughly tested and endorsed by chiropractors, orthopedists, rheumatologists, neurologists, and neurosurgeons.

How is this different from a normal spacer or splint?
Spacers and splints only hold your toe while you wear them.
This device also uses EMS to activate the muscle that helps
keep your toe straight, so it supports both alignment and
muscle training.
What's the abductor hallucis?
It is a muscle along the inside of your foot that helps keep
your big toe in line. When it becomes weak, the toe may drift.
EMS stimulation helps activate this supporting muscle.
Does the EMS hurt?
It should feel like a light tingling sensation that builds
into a gentle contraction. You can adjust the intensity to
your comfort level.
How fast will I feel a difference?
Some people notice less pressure within the first few
sessions. Muscle strengthening generally develops gradually
over several weeks of consistent use.
How long do I wear it?
Use it for approximately 15 minutes a day while seated and
relaxed.
What if it doesn't work for me?
Please review the return and refund policy provided with
your order, or contact the support team for assistance.

At 62 I did not expect much, but the pressure on the side of my foot is noticeably lower. It's comfortable enough that I forget I have it on, and my toe is sitting straighter than it has in years.
Margaret K. Verified Buyer
★★★★★
I tried toe spacers and a night splint before this and nothing held. What sold me is that the muscle actually feels like it's working. I use it while watching TV — it fits my routine easily.
David T. Verified Buyer
★★★★★
For the first time in a long while I'm not hiding my feet in sandals. The pain that used to flare up after a day of standing has calmed right down. I only wish I'd found this sooner.
Susan L. Verified Buyer
★★★★★
My doctor mentioned surgery and it frightened me. I wanted to try something first. Six weeks in and the bump hasn't grown, the ache is far milder, and honestly it's the only thing that's given me hope without going under the knife.
Barbara W. Verified Buyer
★★★★★
I'm on my feet all day as a nurse and my big toe was constantly throbbing by evening. I was skeptical about the EMS but the tingling is gentle. After a month the evening pain is almost gone. Simple to charge and use.
Linda M. Verified Buyer
★★★★☆
Took me about two weeks to notice a real change, so don't give up early. The build quality is solid and the strap fits my wider foot. Would've liked a travel case, but the results speak for themselves.
