Abstract: A suction-preventing footwear includes a boot, a first-vent, a second-vent, a third-vent, a manifold, and a one-way valve. The boot may include a sole having a heel and toe, as well as an upper extending above the sole for covering a user's foot having a vamp, a boot shaft, and a cuff. The first-vent may be affixed to the boot shaft near or on the cuff. The second-vent may be affixed to the top of the vamp, and the third-vent may be affixed to the rear of the boot shaft above the heel of the sole. The manifold may join the first-vent, the second-vent, and the third-vent together, such that each is in fluid communication with the others.
