Abstract
A shoe includes a sole for cushioning a heelstrike. The sole includes a midsole, an optional outsole, and a resilient cushioning device. The resilient cushioning device includes a bottom component, a top component sealingly attached to the bottom component, wherein the top component includes a corrugated sidewall. The resilient cushioning device is a closed system that contains a fluid, such as a gas either at atmospheric pressure or pressurized. The resilient cushioning device may have only one interior compartment or a series of compartments fluidly connected to one another. The resilient cushioning device is partially embedded within the midsole in a heel region of the sole, although at least a portion of the sidewall of the resilient cushioning device remains visible from the exterior of a shoe sole.
