Lack of mechanical support and poor integration between inflatable components and footwear uppers. Resolving this prevents material shifting and ensures consistent anatomical support during high-impact movement.

Repeated mechanical loading causes standard fluid bladders to deform unevenly or bottom out under high pressure. Reinforcing and stacking bladders prevents structural failure and maintains consistent energy return across the footbed.

Localized pressure spikes and uneven support surfaces in wearable inflatables cause discomfort and reduced structural integrity. Uniform pressure distribution ensures ergonomic fit and predictable mechanical response across complex geometries.
