Full palm carbon fiber insoles for shock absorption and high elasticity running and sports, available in multiple sizes from 34 to 48 UK and three thicknesses of 0.8mm, 1.0mm, and 1.2mm for a custom fit
Full Palm Carbon Fiber Insoles for Shock Absorption in Running and Sport

These 3K full palm carbon fiber insoles are designed for activities like running where shock absorption and energy return are beneficial. The product listing highlights their non-deformable and corrosion-resistant properties, which suggest a focus on maintaining performance over time. Offered in a practical black colour, they come in a wide selection of sizes from UK 34 to 48, making them suitable for a broad range of users. A key feature is the choice between three specific thickness measurements—0.8mm, 1.0mm, and 1.2mm—allowing you to personalise the insole's profile within your shoe for optimal comfort and fit.
Features and Construction

The core specification centres on the 3K full palm carbon fiber build and the available customisation options. This section details the material's stated characteristics and how the sizing and thickness choices work.
Material and Build
The insoles are constructed from 3K full palm carbon fiber. The source text specifically notes this material is non-deformable and corrosion-resistant. In practical terms, a non-deformable structure aims to retain its shape and support under the pressure of footstrike, which can be valuable for consistent performance. Corrosion resistance suggests a material that is less susceptible to degradation from moisture or sweat over time, contributing to the product's potential longevity.
Size and Practical Fit
A comprehensive size range from UK 34 to 48 is offered, covering many common foot lengths. More notably, you can select from three precise thickness options: 0.8mm, 1.0mm, and 1.2mm. This choice lets you manage the volume the insole takes up inside your shoe. A thinner 0.8mm option may suit snug-fitting trainers, while a 1.2mm version could offer more cushioning or fill extra space in a larger shoe, helping to achieve a secure, customised fit.
Uses and Placement

The product's described functions point towards active use. Here we explore the intended scenarios and how to integrate the insoles into your gear.
Event or Professional Use
With features like shock absorption and high elasticity highlighted, these insoles are positioned for demanding physical activities. Runners, in particular, may find value in the shock-absorbing quality to reduce impact on joints, while the high elasticity is intended to contribute to energy return with each step. The non-deformable carbon fiber construction aims to provide stable, reliable support throughout training sessions or competitions, where consistent equipment performance is often sought.
Everyday Home Use
While optimised for sport, the properties of these insoles could also be relevant for everyday active wear. The shock absorption may offer comfort during prolonged standing or walking, and the corrosion resistance is a practical benefit for insoles exposed to daily perspiration. The full palm design provides support across the entire footbed, which can be preferable for all-day wear compared to partial or heel-only inserts.
Benefits and Buying Value
The value of this product lies in its material specification and the ability to tailor the fit. This section covers the practical advantages these factors provide.
Reuse and Low Maintenance
The corrosion-resistant nature of the carbon fiber material implies a degree of durability and ease of maintenance. This characteristic suggests the insoles can withstand exposure to sweat and moisture better than some materials, potentially extending their usable life across multiple training cycles. Their non-deformable quality also indicates they are designed to resist flattening or breaking down quickly, supporting repeated use.
Why Choose This Product
The decision point for this product revolves around its specific material choice and customisation. If you are looking for insoles utilising carbon fiber for its stated properties of being non-deformable and corrosion-resistant, this is a clear option. Furthermore, the availability of three exact thicknesses is a distinct functional advantage, allowing you to fine-tune the fit in a way that generic, one-thickness insoles cannot, making it a solution for achieving a more personalised feel in your footwear.
