D

Dorsiflexion: Movement of the foot towards the shin bone in the sagittal plane. To learn more, View The Sagittal Plane

Double Support (DS): The period of time when both feet are in contact with the ground. This occurs twice in the gait cycle, at the beginning and end of the stance phase. Also referred to as left and right double limb stance or LDLS and RDLS respectively. For example, LDLS refers to the DS after left initial contact.

DuoMax®: A proprietary ASICS® system consisting of two or more different density midsole materials, designed to help correct the degree and velocity of pronation.

DuoSole®: A proprietary approach to outsole construction offering light weight, flexibility, traction and durability.

DuoTruss® System: A dual-density reinforcement which provides torsional stability and biomechanically balanced arch support.

DuraSponge®: A blown AHAR® rubber compound for enhanced cushioning and durability in the forefoot.

Dynamic Cradle™: A molded midsole component engineered for specific foot types to enhance guidance and fit.

E

Eversion: Outward turning of the rearfoot. To learn more, View The Frontal Plane

F

Foot Flat (FF): The point in time in the stance phase when the entire foot is in contact with the support stance.

Frontal Plane: The Frontal Plane divides the body into front and back halves. To learn more, View The Frontal Plane

G

Gait Cycle: The period of time from one event (usually heel contact) of one foot to the following occurrence of the same event with the same foot. To learn more, View Gait Cycle

Gait Stride: The distance from initial contact of one foot to the following initial contact of the same foot.

H

Heel Contact (HC): When initial contact is made with the heel. Also known as heel strike.

Heel Off (HO): The point in the stance phase when the heel leaves the ground.

I

I.G.S.® (Impact Guidance System): Meeting the demands of all athletic activities, the I.G.S.® (Impact Guidance System is a technical design philosophy that allows the foot to perform in a more natural manner.

Initial Contact (IC): The point in the gait cycle when the foot initially makes contact with the ground: this represents the beginning of the stance phase. It is suggested that heel strike not be a term used in clinical gait analysis as in many circumstances initial contact is not made with the heel.

Initial Swing: The initial third of the swing phase from 60 to 73% of the gait cycle as defined from toe-off to when the swing limb foot is opposite the stance limb. To learn more, View The Swing Phase
