Standard fluid chambers fail to match complex anatomical contours of the foot. Improving geometric fit prevents localized pressure points and mechanical instability.

Internal fluid pressure causes uncontrolled expansion or bulging in flexible containers. Controlling this geometry ensures consistent mechanical response and prevents material fatigue.

Standard textiles lack the necessary internal void space to maintain fluid displacement or mechanical loft under load. Increasing the three-dimensional gap between layers prevents physical collapse and improves energy absorption.
