3K full palm carbon fiber running insoles for shock absorption and high elasticity, available in thicknesses of 0.8mm, 1.0mm, and 1.2mm, in black for men's and women's sizes from 34 to 48.
3K Full Palm Carbon Fiber Insoles for Running Shock Absorption and Elasticity

Designed for the practical needs of runners, these insoles provide a structural upgrade to athletic footwear through their core material: 3K carbon fiber. The "full palm" design offers consistent support across the entire footbed, aiming to address impact shock during runs. Their primary stated functions are shock absorption and high elasticity, which are intended to work in tandem to reduce strain and return energy. Available in three specific thicknesses and a wide range of sizes, they allow for a tailored fit and feel based on individual preference and shoe type, without the need for complex customisation.
Features and Construction

The construction of these insoles centres on the properties of 3K carbon fiber. This material choice informs the product's key characteristics, which are presented as factual benefits for running activities.
Material and Build
The use of 3K full palm carbon fiber is the defining feature. This material is noted for being non-deforming and corrosion-resistant, suggesting it will maintain its shape and integrity over time despite moisture and pressure. The "full palm" coverage means the carbon fiber support extends across the entire insole area, from heel to toe, rather than being placed in isolated sections. This provides a uniform platform designed to manage the forces of running across the whole foot.
Size and Practical Fit
A practical advantage of these insoles is their extensive size range, covering EU sizes 34 through 48. This range accommodates both men's and women's footwear. The availability of three precise thicknesses—0.8mm, 1.0mm, and 1.2mm—is a key functional differentiator. A runner can select a thinner option for a more minimal feel or a thicker one for increased cushioning and arch lift, depending on their shoe's internal volume and personal comfort requirements.
Uses and Placement

These insoles are presented as a dedicated solution for running. Their application is straightforward, focusing on replacing standard shoe insoles to modify the underfoot experience.
Event or Professional Use
For runners engaging in regular training or events, the shock absorption property is intended to mitigate the repetitive impact on joints. The high elasticity is designed to provide a responsive feel, which can be particularly relevant for tempo runs or races where energy return is valued. The corrosion resistance adds a practical durability aspect, suggesting the insoles can withstand sweat and varied weather conditions encountered during outdoor running.
Everyday Home Use
For the everyday runner, the main benefit is the potential for customised comfort and support. The process is simple: remove the existing insole from your running shoe and replace it with the carbon fiber version in your chosen thickness. This allows you to adapt different pairs of running shoes—perhaps a daily trainer and a race-day shoe—with the same consistent footbed feel, using the product's properties as a stable foundation for various running disciplines.
Benefits and Buying Value
The value proposition hinges on the material's stated longevity and the flexibility offered by the thickness options. It is an investment in a durable component that can be transferred between shoes.
Reuse and Low Maintenance
The non-deforming and corrosion-resistant nature of the carbon fiber implies low maintenance. Unlike foam insoles that can compress over time, these are designed to retain their shape. This means they can be reused across multiple shoe lifecycles, potentially outlasting several pairs of running shoes. Care is minimal, typically involving occasional wiping clean, as dictated by the material's properties.
Why Choose This Product
This product is a choice for runners who prioritise a firm, supportive, and responsive footbed over soft, plush cushioning. The 3K carbon fiber construction offers a distinct feel compared to gel or foam insoles. The ability to select a specific thickness allows for precise tuning of shoe fit and stack height. When choosing, consider your existing shoe's internal space and your preference for underfoot firmness to decide between the 0.8mm, 1.0mm, or 1.2mm options.
