Shoe having a rear attachment element (5) joined to a mobile support (6)
that moves from an open position in which it is separated from the heel
of the foot and a closed position in which it holds the heel piece, also
connected to a mechanism housed in said heel piece (3), which mechanism
can be actuated by applying pressure with the heel of the user's foot on
the heel piece (3) to displace the mobile support (6) from the open to
the closed position, where it is kept by first retaining-releasing means
(10, 26, 50, 70, 90, 100, 110, 120, 130, 140, 150, 160), while the other
foot of the user acts on a member (24, 36, 51, 71, 91, 101, 111, 121,
131, 141, 151, 152) of the mechanism for moving said mobile support (6)
from the closed to the open position, where it is maintained by second
elastic retaining-releasing means (7, 25, 52, 72, 92, 102, 112, 122, 132,
142, 152, 162).
