A natural latex and binchotan deodorising insole covered by invention patents in several territories.
- TakeSoft: Guang Xin's own brand, natural latex compounded with binchotan charcoal at high density, covered by invention patents in several territories
- Deodorising is physical adsorption: the vast internal surface of porous carbon traps odour molecules; no fragrance is used to mask them
- Breathability is a dynamic pump: open honeycomb cells expel warm damp air when compressed and draw dry air in on release

1. TakeSoft: two natural materials in one insole
The interesting part of TakeSoft is not that it contains latex and charcoal, but that the two are compounded at high density rather than layered. Natural latex supplies the elastic body and the open-cell structure; binchotan charcoal supplies the porous surface area. Compounding them into one material means the function sits in the body of the insole, so it does not disappear as the surface wears.
The route is deliberately a natural, non-toxic one. That has a consequence worth stating plainly: natural latex is tapped from the rubber tree and carries natural proteins, and a small number of people are allergic to them. We recommend the finished product declares its composition so buyers can judge for themselves.

Third-party test reports
Reports obtained on TakeSoft latex from independent laboratories. The data corresponds to the submitted sample; a brand publishing a claim should have its finished product tested in its own right.

Where a patent is marked on packaging, a label or an advertisement, most jurisdictions regulate how it is marked and which number is disclosed, and false marking can amount to misleading advertising. We suggest marking specifically — "Invention Patent No. I349531" — and stating the technical feature the right covers, rather than letting the word "patented" stand for the whole product.
The Chinese document is a trademark registration, not an invention patent; do not describe it as a Chinese patent, and confirm the registration is still in force before citing it.

3. Deodorising: the pores are what matter
Charcoal deodorises by adsorption, which is a physical process, not a chemical one. Binchotan is fired so that it develops an enormous internal network of micropores; odour molecules entering those pores are held there. Nothing is released and nothing reacts, which is why the material does not create a second smell of its own.
4. Breathability is a pump, not a set of holes
Punching holes in a closed-cell foam does not make it breathe. Air has to have somewhere to go. TakeSoft uses an open honeycomb foam whose cells connect, so the insole behaves as a pump driven by walking: body weight compresses the cells and forces warm damp air out; lifting the foot lets the foam recover and pulls dry air back in.
The forefoot drainage nubs work with the same principle at a local scale, adding a direct air path under the ball of the foot as well as a tactile massage effect.
5. Far infrared, stated precisely
Porous carbon materials are described in the literature as absorbing and re-radiating in the long-wave infrared band. That is a physical property of the material and it is the only thing we state.
6. The patented 3D cup heel
The heel fat pad is the body's own shock absorber, and its performance depends on staying where it belongs. Under load on a flat insole the pad spreads sideways, which is exactly when its cushioning is least useful. A three-dimensional cup wraps the heel from both sides and behind, keeping the pad centred so the absorption stays concentrated under the heel bone.
The same walls limit lateral travel of the heel, which reduces roll. Cup depth is a design constraint, not a case of deeper being better: it has to suit the internal height of the shoe, or the cup fouls the shoe wall and the fit is worse than a flat insole would have been.
7. Latex, PU or EVA: the claim decides
| Material | Best for | Watch out for |
|---|---|---|
| Natural latex / TakeSoft | Natural material story, fine rebound, breathability | Protein-bearing; declare the composition |
| PU | Stable rebound, resists collapse under long standing | Higher unit cost; formulate against hydrolysis |
| EVA | Lowest weight and cost | Compression set becomes visible with use |
| Memory foam | Envelopment and even pressure | Stiffens cold, holds heat |
Detailed construction options — single versus dual density, one-shot fabric moulding versus post-lamination — are on Insole OEM / ODM.
8. ESG and the green supply chain
For a brand under supply-chain scrutiny the material route is itself a procurement argument. Natural latex is a renewable, plant-derived raw material, and a physical deodorising mechanism avoids the residue questions that come with released chemical agents. Where a customer requires substantiation we can supply material and process information for their own assessment; we do not issue environmental certifications on their behalf.
9. Frequently asked
TakeSoft is Guang Xin's patented green latex insole material: natural latex compounded with binchotan charcoal fibre at high density, covered by invention patents in more than one territory. The positioning is a natural, non-toxic materials route with five functional directions — deodorising, anti-mould and antibacterial, breathability, far-infrared emission and sustainability.
By physical adsorption, not masking. Binchotan is a highly porous carbon whose enormous internal surface area traps odour molecules inside its micropores. Because no fragrance is added, there is no second smell layered on top of the first. The trade-off is that adsorption capacity is finite, so the product should be aired and dried rather than assumed to work indefinitely.
No. It comes from the open honeycomb foam structure acting as an air pump. Each footfall compresses the cells and pushes warm damp air out along the open pores; lifting the foot lets the foam recover and draw dry air back in. One step is one complete air exchange, which is why an open-cell structure outperforms a closed-cell one with holes punched through it.
It describes a physical property of the material: absorption and re-radiation in a particular long-wave band. Physiological effects attributed to far infrared remain a research topic, so we make no therapeutic claim and recommend brands do not either. Where a figure such as emissivity is to be published, it should come from a finished-product test under a method such as FTTS-FA-010.
It constrains the heel fat pad. Three-dimensional side walls wrap the heel from both sides and behind, keeping the fat pad centred so its natural shock absorption stays concentrated under the heel bone instead of spreading sideways. The same walls limit lateral roll. Cup depth has to be designed against the internal height of the shoe: too deep and it fouls the shoe wall.
The claim decides the material. Latex for a natural-material story with fine rebound and good breathability; PU for stable rebound and resistance to collapse under long standing; EVA where low weight and low cost lead. Natural latex is a protein-bearing material, so the finished product should declare its composition.
Not straight from material literature. The reports on this page correspond to the samples submitted, not to your finished product. To publish a figure, the finished item must be tested under the corresponding method — AATCC 100 or ISO 20743 for antibacterial work — with the method and organism stated. We supply process and material information to support the submission.
