Product Description
Fusion Flexi Fusion Flexi Lite
■Excerpt from Manufacturer Description
■Regarding peeling of core material and nonwoven fabric parts
〇Reason for peeling occurrence
The FUSION-FLEXI series adopts a special core material structure that combines flexibility and resilience.
On the other hand, non-stretchable nonwoven fabric is used on the toe part to enhance strength.
At the junction of these different materials, load is applied with each step or movement, causing repeated shape changes.
As a result, even if there is no problem at the initial bonding stage, peeling may gradually occur with continued use.
Especially in CORE and MARSHMALLOW, non-stretchable nonwoven fabric is adopted prioritizing durability, so peeling tends to be more noticeable.
Furthermore, since CORE is designed with a higher lateral arch, peeling may also occur during the manufacturing stage.
○Impact on functionality
Although it may cause discomfort visually, peeling does not affect the functionality of the insole.
We hope you can use it with confidence.
Also, please understand and accept this as a characteristic of the product before ordering.

The sports insole "FUSION-FLEXI," born from the technology of a long-established domestic prosthetics and orthotics manufacturer and the experience and knowledge of a former athlete, differs from conventional sports insoles by following foot movement and not hindering its motor function, achieving a holding sensation like part of the body through the effect of the insole between the shoe and foot.
Many of its users were competition-oriented athletes, but finally, "FUSION-FLEXI LITE" has appeared as an all-round insole that adapts to everyday life, work, and all kinds of sports.
"FUSION-FLEXI" was developed for those more competition-oriented, focusing on thickness, cushioning, and stability.
On the other hand, "FUSION-FLEXI LITE" was developed with the desire to protect the feet of various users, improving the foot mold, which is the key to insole making, based on accumulated technology.
The specifications and materials of the insole were reviewed from scratch.
As a result, cushioning and durability have improved compared to previous models.
It reduces fatigue from harsh training environments and, while securing the stability characteristic of "FUSION-FLEXI," also plays a role in injury prevention.
Because it "wants to be the new standard for sports insoles," "FUSION-FLEXI LITE" boldly upgraded functions while being more affordable than previous models.
You should feel "something is different" from the moment you wear it.
"FUSION-FLEXI LITE" is delivered to everyone as the highest standard insole that is gentle on the feet.
・Uses a soft new material cushion with 4mm thickness
・The new material cushion also has high durability and grip
・The wall height is set lower than other models, designed for comfort
・The arch shape has been improved from previous models to enhance fit
*Since manufacturer images are used, specifications (logo position, color, pattern position, etc.) may differ slightly from this product.
