3K Full Palm Carbon Fiber Insole for running shoes provides enhanced shock absorption and high elasticity, available in black with thickness options of 0.8mm, 1.0mm, or 1.2mm to fit shoe sizes from EU 34 to EU 48.
3K Carbon Fibre Running Insoles: Precise-Thickness Insoles for Shock Absorption

Upgrade your running experience with these technical insoles crafted from 3K full palm carbon fibre. Designed as a direct replacement for standard shoe liners, they bring a distinct combination of structure and resilience to your footwear. The primary benefit is their stated function: providing high elasticity and shock absorption specifically for the impact forces generated during running. Available in a comprehensive range of sizes from EU 34 to 48 and in a discreet black colour, they offer a practical solution for runners seeking durable, performance-oriented foot support without compromising on fit, thanks to the three selectable thickness options.
Features and Construction

The core of this product's performance lies in its specific material and the available sizing choices, which are tailored for a functional fit in running shoes.
Material and Build
The insole is constructed using a 3K full palm carbon fibre. This refers to a specific weaving pattern where each strand consists of 3,000 individual carbon filaments, creating a dense, woven fabric. This construction is directly linked to the stated properties of being non-deformable and corrosion-resistant, meaning the insole is designed to retain its intended shape and resist degradation from moisture or sweat over time. The high elasticity mentioned is a characteristic of this carbon fibre weave, contributing to the shock absorption capability that returns energy with each footstrike.
Size and Practical Fit
These insoles are offered in a wide spectrum of standard European shoe sizes, from EU 34 to EU 48, ensuring compatibility with most adult running shoes. A key differentiator is the choice of three precise thickness measurements: 0.8mm, 1.0mm, and 1.2mm. This allows you to fine-tune the internal volume of your shoe. A thinner 0.8mm option is suitable if your shoe fits snugly, while the 1.2mm version can fill more space or provide a more pronounced platform feel. All variants come in a uniform black colour, designed to blend discreetly with the interior of most athletic shoes.
Uses and Placement

These insoles have a clear, defined purpose centred on athletic performance and everyday durability, replacing generic insoles for a more supportive experience.
Event or Professional Use
For dedicated runners, these carbon fibre insoles are intended for use during training runs and races. The shock absorption property is specifically aimed at mitigating the repetitive impact forces on joints during running. Their non-deformable nature suggests they are built to withstand the rigours of consistent, high-intensity use, maintaining their supportive structure mile after mile where standard foam insoles might compress and lose effectiveness.
Everyday Home Use
Beyond dedicated running, the corrosion-resistant and durable construction makes these insoles a practical choice for all-day wear in casual or work shoes where support is desired. Their ability to retain shape makes them a long-lasting replacement for worn-out original insoles in any footwear, providing a consistent feel. The simple act of removing the factory insole and inserting this carbon fibre version can refresh an older pair of shoes.
Benefits and Buying Value
The value proposition of these insoles is grounded in their material longevity and the practical advantage of a customisable fit.
Reuse and Low Maintenance
The non-deformable and corrosion-resistant qualities of the carbon fibre suggest a product designed for extended use. Unlike some foam or gel insoles that can break down, these are intended to maintain their profile and functional properties over time. Care is straightforward: they can be wiped clean with a damp cloth if needed, aligning with the low-maintenance aspect implied by their resistant materials.
Why Choose This Product
Choose these insoles if you require a durable, structured replacement insole that offers stated shock absorption for running. The key decision points are the precise thickness option (0.8mm, 1.0mm, or 1.2mm) and ensuring your exact EU shoe size is available from the listed range. They represent a material upgrade focused on resilience and consistent performance, moving away from disposable foam inserts towards a more permanent footwear component.
