However, in such a dangerous situation during use, since it often causes strong pressure or impact, or damage due to contact with mud or mud, one or more tightening devices are used. If the element is damaged or severely damaged, it is necessary to perform a desired replacement at a predetermined frequency.

Because the fastening elements are fixed to the instep, replacing one or more of the elements is a rather tedious task, and requires skilled craftsmen to sew or rivet the instep skin appropriately. Technology is required. All such replacement work cannot be performed by a normal user.

Further, in the above-described construction, manufacturers who use different types of fastening devices to form boots, even if they are on the same upper, will produce identical boots for those fastening devices. Obviously, it must be preserved and kept. This is of course
Not practical and uneconomical.

The technical problem proposed by the present invention is
In particular, but not exclusively for this purpose, it is to provide a cross-country oriented fastening device, which facilitates the exchange of one or more elements with each fastening device.

[0008]

This object is achieved according to the invention by the fastening device described above having the following features. That is, the device is such that at least one of said elements is releasably attached to a corresponding instep flap by anchor means, said anchor means being attached to said flap and defining a socket. And a second anchoring device attached to a corresponding tightening element is releasably received in an intertwined manner in the socket. The features and advantages of the present invention will be apparent from the following description of preferred, but not exclusive, embodiments with reference to the drawings.
