The invention relates to a shoe, in particular a sports shoe, with a shoe upper part and an outsole joined to the latter, and also with a heel shell, which at least partially encloses the heel of the wearer of the shoe. The device includes a radio that enables bidirectional data communication between the device and the at least one wireless access point, the radio being able to operate in a power save mode and an active transmission mode. Access relationships are created between players in a cooperative game and variables in a multivariate statistical model.
