[Function/Material]

■ MATRYX® upper [+TPU reinforcement]
The upper is made of a tough multifilament of Kevlar fiber and high-strength polyamide. It boasts excellent abrasion resistance and suppresses stretching, ensuring the durability and stability of the upper. By using MATRYX® as a base, it was possible to review the upper pattern, which resulted in successfully reducing the number of overlay parts. Achieved a structural design that is lighter and more breathable. 37.5® Tongue Lining and Mesh Footbed Cover <br>A special system structure in which micropores of active particles increase the surface area of ​​the fibers removes moisture at the water vapor stage (allowing moisture to escape) and improves comfort inside the foot chamber.■ Recycled shoelaces
Shoelaces made from 100% recycled materials

Elasticated keeper to store laces after tying
■ Recycled tongue webbing

■ BZM-8 Lock Plate & FLEXPLATE™
The plate is made from BZM-8 (glass fiber reinforced polyamide), which is highly rigid and fatigue resistant. Its excellent rigidity improves performance when stepping on the ground, suppresses twisting of the shoe, stabilizes the sole of the foot, and protects the foot from impact with the ground.
■ FLOATPRO™ foam two-layer midsole
A sustainable EVA foam that has excellent cushioning and resilience, and is lightweight and durable (functional sustainability). To reduce the burden on the environment, it is made using a "waste-free manufacturing process" and is made from TPE (thermoplastic elastomer) material, which is easier to recycle. It is used in the midsole in a two-layer structure that sandwiches the BMZ-8 rock plate.
■ Vibram MEGAGRIP outsole
This is one of the best high performance compound grips from Vibram, a world-renowned Italian sole manufacturer. It provides overwhelming grip on wet roads and rugged terrain. We paid particular attention to the lug pattern and lug depth (5mm), which affect grip on the field, and reduced the rubber area to the maximum extent possible to reduce weight.
