Understanding Gait Analysis and Insoles | ErgonX

The Phases of the Gait Cycle

Walking and running consist of two main phases: the swing phase and the stance phase. Gait analysis focuses primarily on the stance phase, where the foot makes contact with the ground. This phase is broken down into contact, midstance, and propulsion. During contact, the foot naturally pronates slightly to absorb shock and adapt to terrain. However, excessive pronation during midstance can cause the leg to rotate internally, putting excess strain on the foot, ankles, knees, and lower back.

How Arch Support Controls Excess Motion

Rather than aggressively wedging the heel, effective orthotic insoles support the calcaneal inclination angle and contour the medial arch. Supporting these key anatomical structures helps limit overpronation while preserving natural foot movement. When combined with a supportive, properly fitted shoe, orthotic insoles help maintain proper alignment across flat, high-arched, or neutral foot types, reducing stress-related strain during daily activity.

Key Takeaways From Gait Analysis

• Pronation is a natural shock-absorption movement, but overpronation strains muscles and joints.
• Evaluating your stance phase helps determine whether you need additional medial arch support.
• A proper combination of supportive shoes and orthotic insoles helps stabilize foot motion without over-correcting.
