Key Features
900+ Gauss, Everywhere
A genuinely strong surface field of 900+ Gauss spread uniformly across the entire sole — not a few scattered, low-strength magnet dots.
Single-Sided Multipole Magnetization
A tight 5 mm pole pitch: N and S alternate every 5 mm in parallel bars — fine, even stripes under magnetic-viewing film, and a dense rhythm of field reversals underfoot with every stride.
Fundamentally Different
Traditional insoles embed magnets at a few spots, with small coverage and weak strength. Full-field coverage acts on the sole more comprehensively and deeply.
Soft · Durable · Rust-Free
A soft, skin-friendly feel that holds up to daily wear and shrugs off rust over the long haul.
Trim to Any Size
Cut along the printed guide lines for a tailored fit — suitable for the great majority of men's and women's feet.
Soft as Cotton, Strong as Steel
Trim to fit — comfortable all day long
This is not a rigid magnetic slab — it's an insole you can genuinely wear every day. The body is highly elastic, bending naturally with the arch of your foot: nothing digs in, nothing presses back.
Finished in a matte black with a quietly premium feel, the surface is soft and skin-friendly, wear-resistant and rust-free — and the magnetism stays as strong as day one through long-term use.
Bends With Your Arch
Highly elastic — it flexes naturally along the arch of the foot, never digging in or pressing back.
Skin-Friendly, Magnetism Like New
A soft, skin-friendly surface that resists wear and rust — the field stays as strong as ever through long-term use.
Trim-to-Fit Design
Cut easily along the printed guide lines — fits the great majority of men's and women's shoe sizes.
On your feet all day at work — the sole underfoot stays springy and comfortable.
Sports, commuting, everyday wear: strong magnetics that genuinely fit into daily life.
Magnetism Across Every Inch
Place it under magnetic-viewing film and the single-sided multipole magnetization shows itself plainly: alternating N–S (+ − + −) bars at a 5 mm pitch blanket the entire surface — not a few isolated magnet dots.
It is this complete, uniform layout — one pole transition every 5 mm — that lets the magnetism reach every part of the foot that touches the insole, comprehensively and not selectively.
Seen in Simulation: A Field That Stands Up From Every Inch
This 3D magnetic-field simulation makes the invisible visible: across the entire insole surface, field vectors rise like a dense forest, wave after wave following the 5 mm-pitch alternating N–S bars — nowhere flat, nowhere empty.
The ridged, repeating peaks are the signature of the alternating-pole layout: each N–S boundary concentrates flux right at the surface, exactly where the sole of the foot rests. What the magnetic-viewing film shows as stripes, the simulation reveals in full three-dimensional relief.
Field Across Every Inch
Field arrows rise from the entire surface — proof the magnetism blankets the whole insole, not a few isolated spots.
Peaks Every 5 mm
At a 5 mm pole pitch, flux concentrates at each N–S boundary — dozens of interaction zones across a single stride, right where the foot meets the insole.
Engineered, Not Guesswork
The layout is modelled and verified in magnetic simulation, the same way we engineer our industrial magnet assemblies.
Walking Turns the Field Dynamic
The surface is magnetized single-sided and multipole at a 5 mm pitch: N and S poles alternate in parallel bars every 5 mm. As you walk, the sole of the foot is in constant motion against this field, interacting with it step after step.
Because the poles alternate every 5 mm, the foot passes over a dense pattern of field reversals — and the natural rise and fall of walking amplifies that physical interplay. By the principles underlying Faraday's law of electromagnetic induction, this interaction may give rise to subtle local induction effects, creating a distinctive magnetic environment for the foot with magnetism accompanying every step.
Alternating Poles
Single-sided multipole magnetization at a 5 mm pitch lays N–S poles in parallel alternation across the whole sole.
Dynamic Interaction
With every stride, the foot sweeps across a dense zone of magnetic-field changes.
Faraday's Principle
Motion through a changing field may induce subtle local effects — a unique magnetic environment underfoot.

Acupressure Dots · Foot Reflex Zones
The diagram is a traditional foot-reflexology reference; zone positions are illustrative and not a basis for medical diagnosis.
The surface is covered in raised bumps that press gently into the sole as you walk or stand. In traditional foot care, the sole maps to reflex zones across the whole body, and gentle pressure helps the feet unwind and eases the strain of long hours on your feet.
Add the rare-earth field on top, and every step becomes a continuous, gentle massage underfoot.

Nerve Pathways · Blood Flow · Every Step
The feet are a nexus of nerve endings and blood vessels, intricately connected to systems throughout the body. When the SmFeN rare-earth field and the raised massage dots work in unison underfoot, every step delivers a gentle, continuous stimulus to those pathways.
Supporting healthy circulation from the ground up is one of the simplest investments in daily wellness — and with a full-surface magnetic field under your sole, the insole keeps working quietly with each and every step, no extra effort required.

Design Story · Vitality in Every Curve
The flowing spiral “clouds” across the insole are far more than decoration — they evoke vitality and the free flow of energy, bringing the visual design and the full-surface raised texture into one.
Spiral Clouds
Flowing spirals that evoke vitality and the circulation of energy — lively and full of vigour.
Raised Surface Texture
The whole insole is magnetic material; raised bumps across the surface massage the sole with every step.
Full-Surface Field
A 5 mm-pitch alternating N–S field covers the entire surface for all-round contact with the foot.

About the Material
The magnetism comes from samarium iron nitrogen (SmFeN), a fourth-generation rare-earth permanent magnet — explore the material behind it.

Frequently Asked Questions
Answers to common questions about our magnets, customisation, ordering and shipping.
- What is the SmFeN magnetic insole? +
- A fourth-generation samarium iron nitrogen (SmFeN) rare-earth magnetic insole. Using single-sided multipole magnetization at a 5 mm pole pitch, it lays N and S poles in alternating parallel bars every 5 mm across the entire surface, spreading a 900+ Gauss field evenly over the whole sole — wherever the foot lands the magnetism is already there. Soft, skin-friendly, wear-resistant and rust-free.
- How is it different from ordinary magnetic insoles? +
- Ordinary insoles embed a few scattered, low-strength magnets at just a few spots — small coverage, weak field. This one uses single-sided multipole magnetization at a 5 mm pole pitch to form one complete, uniform 900+ Gauss field surface that blankets the whole sole — verified under magnetic-viewing film and 3D field simulation — so its action on the foot is broader and deeper.
- How does it work as you walk? +
- Alternating N–S poles at a 5 mm pitch create a dense pattern of field changes across the surface. As you walk, the foot moves dynamically against this field, crossing a new pole boundary every few millimetres — and by the principles underlying Faraday's law of electromagnetic induction that interaction may produce subtle local induction effects — a distinctive magnetic environment accompanying every step. It is a daily-wellness product, not a medical device.
- What are the raised dots on the surface for? +
- The surface is covered in raised bumps that press gently into the sole as you walk or stand. In traditional foot care the sole maps to reflex zones across the whole body; the entire insole is SmFeN permanent-magnet material with magnetism across the full surface. Gentle pressure plus the rare-earth field turn every step into a continuous, gentle underfoot massage.
- Can I trim it to fit my shoe size? +
- Yes. The insole is unisex and trims neatly along the printed guide lines to match almost any men's or women's foot size. It is a flexible composite that bends with the arch and springs back into shape.
- Is it comfortable and durable enough for everyday wear? +
- Yes — it is not a rigid magnetic slab. The body is highly elastic and bends naturally with the arch, so nothing digs in or presses back, even after a full day on your feet. Finished in a quietly premium matte black, the surface is soft and skin-friendly, wear-resistant and rust-free — and because SmFeN is a permanent-magnet material, the magnetism stays as strong as day one through long-term use.
