A cushion device for shoes includes a first bladder and a second bladder with
a
hose connected in communication therebetween. A compressible unit is received in
the second bladder and has an outgoing hose extending therefrom. The outgoing hose
is connected to an inlet of the first bladder. An inlet hose has an end located
outside of the second bladder and the other end of the inlet hose is connected
to the compressible unit. The wearer compresses the compressible unit to inflate
the first and second bladders. When the load is disappeared from the compressible
unit, air is sucked from the inlet hose to assist the compressible unit to return
to the original status.
