A footwear article having a vacuum release mechanism is disclosed. The vacuum release mechanism equalizes pressure to release a vacuum created beneath the footwear article, thereby eliminating an undesired retention of the footwear article in high-viscosity materials such as mud or concrete. The vacuum release mechanism includes at least one check valve disposed in at least one fluid passageway formed in a sole of a footwear article. The at least one fluid passageway fluidly connects an exterior environment with an interior of the footwear article.
