ASICS Glossary

CUSHIONING

• GEL™ CUSHIONING SYSTEM

• FOREFOOT

GEL™ Cushioning System
Enhances shock absorption during propulsion

• RAREFOOT

GEL™ Cushioning System
Absorbs shock during impact phase and allows for a smooth transition to midstance

• FOREFOOT&RAREFOOT

• MIDSOLE MATERIALS

• GENDER-SPECIFIC CUSHIONING

• SOLYTE® MIDSOLE MATERIAL  

A lighter weight midsole compound than ASICS standard EVA and SpEVA®. Also features enhanced cushioning and durability.

• SUPER SOLYTE®

15 % lighter than normal Solyte ® material

• SPEVA® MIDSOLE MATERIAL 

Improves rebound capabilities and decreases midsole breakdown

• SUPER SPEVA®

Offers 20 % more rebound potential than normal SpEVA

• AMPLI-FOAM

AMPLI-FOAM is more durable, more elastic, maintains its shape more consistently, and offers a lot of rebound energy with an intense running experience

• Lasting

The lasting connects shaf t and midsole and ensures the integrity of the shoe while intensifying ground contact.
ASICS offers the following running shoe variants:
blue lasting 45°
yellow lasting 55° and
red lasting 65

• SOLYTE® 45° LASTING / SPEVA® 45° LASTING

Blue lasting 45° provides more cushioning and is more flexible.

• SOLYTE® 55° LASTING / SPEVA® 55° LASTING

yellow lastings with 55° are processed a little more densely to perfectly match the characteristics of the midsole and provide the foot with a stable foundation

• SOLYTE® 65° LASTING / SPEVA® 65° LASTING

Red lasting 65° provides additional stability for runners by limiting midsole deformation which improves the foothold.

• MIDSOLE COMPONENTS 

Placed in the midfoot area, DUOMA X® is a supporting element made from midsole materials providing a higher degree of rigidity and more stability. It reduces possible overpronation before the push-off phase and improves the natural motion sequence. The DUOMA X® supporting element is mainly used in shoes for runners with a tendency to overpronate. It is available in different versions to meet individual needs.

• DUOMAX® SUPPORT SYSTEM

A dual-density midsole system positioned to enhance support and stability, positioned sport-specifically.

• DYNAMIC DUOMAX®

Next generation DuoMax ® system provides greater comfort and enhances gait efficiency.

• DYNAMIC CRADLE

Reinforced EVA component contoured to provide medial and lateral stability

• CLUTCH COUNTER

Exoskeletal heel counter provides improved support and creates improved heel hold

• TRUSSTIC SYSTEMS 

The TRUSSTIC systems are a lightweight stabilisation unit integrated into the midsole just below the arch of the foot. It connects the rear- and the forefoot. It also supports the midfoot in the stance phase and during preparation for the push-off
phase. The midsole is deformed in a controlled way as a direct result of the foot load. The torsional stability of the shoe remains intact, the arch of the foot is stabilised and the sole of the foot is relieved. Ultimately, this reduces the risk of injury and the running shoe simply provides more comfort and safety.

• GUIDANCE TRUSSTIC NEUTRAL 

This system with its moderate stability ensures efficient movement and support throughout the entire roll-over motion.

• GUIDANCE TRUSSTIC STRUCTURED 

Upon ground contact, the energy is transferred into the pushoff motion. The midfoot is particularly well supported.

• PROPULSION TRUSSTIC

Mimics connective tissue in the foot by creating tension as foot enters propulsion stage.

• FLEX GROOVES

These technologies consistently adapt to each foot movement and any running style. From impact to push-off, each movement is supported as the platform between the foot and the ground is secured in each phase. This is achieved by connecting the outerand midsole construction through the integrated flex grooves.
Optimal guidance and stability is achieved by impact loads being absorbed and distributed across the shoe. This supports the most efficient movement of every runner and facilitates a dynamic push-off

• FLUIDAXIS®

Anatomically correct deep flex grooves have been aligned to the joints of the foot. This innovative construction enables the shoe to recognise, adapt, and respond to the athlete’s exact load and positional change from first impact to toe-off.

• GUIDANCE LINE®

The vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency, optimal transition of movement, and smooth transfer of forward energy

• HEEL GRADIENT 

The heel gradient is the difference in height between a shoe’s forefoot and rearfoot. A slight heel gradient promotes faster movements at high speed, e.g. during interval training or competitions. Additionally, the movement amplitude in the calf muscles /Achilles tendon area is increased by a slight heel gradient. This gives you a more dynamic step which increases your speed

• HEEL GRADIENT 3 mm

This 3 mm difference in height between heel and forefoot offers the lowest off-set in the ASICS collection

• HEEL GRADIENT 6 mm

This 6 mm difference in height between heel and forefoot offers a closer feel to the ground and promotes faster movements at high speed

• HEEL GRADIENT10 mm

This 10 mm difference in height between heel and forefoot offers the best biomechanical position to protect forward motion and reduces load on the Achilles tendons, calf muscles, hamstring and back

• MIDSOLE CONSTRUCTION

The system consists of two perfectly coordinated components: the combined midsole construction from two different materials, which is very light and highly regenerative, and the placement of decoupled GEL ™ cushioning elements in the front- and rearfoot areas of the shoe. Both components are integrated into
the I.G.S.™ and work together to ensure a whole new universal adaptability in relation to surface, foot, and running style.

• DUAL DENSITY MIDSOLE 

The full-length dual density midsole features a lower density top layer for improved cushioning and comfort. The bottom layer has a higher density that provides
stability and responsiveness

• FLUIDRIDE®

The latest evolution in ASICS midsole technology. Fluid Ride ® provides the ultimate in rebound & cushioning characterics at minimum weight.

• PLUS 3

3 mm of additional height on women’s models help relieve Achilles tension

• PROPULSION PLATE

The propulsion plate is a special, hardened unit that has been placed in the forefoot for a more efficient propulsion phase

• LAST CONSTRUCTIONS 

This refers to the manner in which the upper is attached to the midsole. The significance of last construction is that the type of last influences the stiffness and flexibility of the shoe

• BOARD LASTING

For stability and durability. Upper is glued to a thin fiber board, then fastened to the midsole

• CALIFORNIA SLIP LASTING

For stability and comfort. Upper is stitched around a canvas or EVA board and directly attached to the midsole

• NATURAL LAST

• HOTMELT OVERLAY 

This is the lightweight alternative to stiched materials to minimize skin irritation and create a perfect fit.

• ENGINEERED MESH: OPEN MESH UPPER

• OUTSOLE MATERIALS 

The new AHAR ®+ material consists of a significantly softer composition. It provides more comfort from first ground contact onwards, ensures better grip in the roll-over phase and overall increased cushioning. In the rearfoot area the carbon content of the AHAR ®+ material has been increased to improve durability. The AHAR ®+ material (DuraSp onge®) used in the forefoot area increases comfort. The innovative material combines flexibility, light weight and durability.
