Carbon CorePerformance Insole
A genuine 3K carbon fiber plate bonded into an anatomical comfort chassis. It stiffens the arch, controls midfoot torsion and returns energy on every push-off — without adding bulk to the shoe.

Six engineering advantages in one insole
Every layer of the Carbon Core is specified for a measurable job — rigidity, weight, comfort or hygiene — and validated on the bench before it goes into production.
Real 3K Carbon Plate
Autoclave-cured 3K carbon fiber with epoxy resin delivers Class III rigidity at a fraction of the weight of steel or TPU shanks.
Ultra-Light Profile
Only 1.2 mm at the plate and 32 g per pair. Adds performance without changing the fit or volume of your footwear.
Torsional Control
Rated at 18 N·m/rad, the plate bridges the heel and forefoot to stop excessive midfoot twist on hard cuts and sprints.
Explosive Energy Return
Stores load at heel strike and releases it at toe-off, measured at 92% energy return for a snappier, less fatiguing stride.
Anatomical Heel Cup
A deep thermoplastic heel cradle locks the calcaneus in place, improving alignment and reducing heel slip inside the shoe.
Breathable & Antibacterial
Moisture-wicking top cloth with silver-ion treatment keeps the foot cool and odour-free through long training sessions.
Five layers. One engineered system.
The plate alone is not the product. It is the way the plate is bonded, cradled and cushioned that decides how the insole feels after 20 kilometres.
- 01
Breathable Mesh Top Cloth
0.4 mmWarp-knitted polyester with silver-ion antibacterial finish. Moves sweat away from the plantar surface and resists odour build-up.
- 02
Anatomical EVA Cushioning
1.3 mmDual-density EVA shaped to the medial arch. Absorbs impact at heel strike while keeping the metatarsal area responsive.
- 03
3K Carbon Fiber Plate
1.2 mmThe structural core. Autoclave-cured 3K twill carbon fibre bonded with high-temperature epoxy, spanning heel to forefoot for rigidity and energy return.
- 04
TPU Stability Bridge
0.6 mmA thermoplastic cradle wrapping the heel and midfoot. Controls rearfoot roll and keeps the plate correctly seated under load.
- 05
Anti-Slip Base Fabric
0.3 mmHigh-friction non-woven backing that grips the shoe lining so the insole stays exactly where you placed it.

Built for every sport that loads the forefoot
One plate, tuned into multiple rigidity grades. We match the layup to the movement pattern of the sport rather than forcing a single stiffness on every category.
Road & Track Cycling
Stiffens the shoe sole so more pedal force reaches the crank instead of being absorbed by foam.
Running & Marathon
Cuts midfoot twist on long road efforts and keeps the arch supported when the legs fatigue late in the race.
Trail & Hiking
Spreads pressure over sharp rock and root, protecting the plantar fascia on long descents with a loaded pack.
Court Sports
Basketball, tennis and volleyball players get a stable platform for hard lateral cuts and repeated landings.
Football & Rugby
Fits low-profile boots without altering cleat fit, adding stiffness for acceleration and kicking power.
Gym & HIIT
A stable, non-compressible base for squats, box jumps and sled work where soft cushioning works against you.

Questions buyers ask before sampling
If your question is not here, message us directly — our engineers answer technical queries within one working day.
Yes. The core is a 3K twill carbon fiber laminate cured with high-temperature epoxy under autoclave pressure. It is not a printed film or a decorative overlay, and we can provide the material certificate with every bulk order.
The complete build is 3.8 mm at the forefoot, which fits most sports and lifestyle shoes without changing your size. For very low-volume racing flats we also offer a 2.6 mm slim version with the same plate rigidity.
Every pair carries printed trim guides from EU 35 to EU 46. Cut along the guide with standard scissors — the carbon plate stops short of the toe area, so the trim is always made through comfort material only.
The minimum is 500 pairs per size run, and sizes can be mixed within that run. For a first project we can split the run across up to four sizes at no extra cost.
Standard samples ship in 7–10 days after the brief is confirmed. If you need a custom last or a specific rigidity grade, allow 12–15 days including one round of revision.
Absolutely. We print or emboss your logo on the top cloth, produce custom woven labels, and pack to your retail specification — poly bag, printed box or FSC-certified carton.
