This invention relates to ski boots.
At present there are various types of ski boots available, generally of plastics construction, which are fastened by a so-called "pneumatic" device.
For this purpose, the inside of the boot comprises bladder members which are inflated by the user after putting on the boot, so as to firmly lock the foot inside the boot.
The air is fed into the bladder members by pumping members connected to suitable delivery and vent valves, which can be removably connected to the bladder members or can be directly incorporated in the boot.
The present invention relates to fastening devices with the pumping means incorporated in the boots, and it is to these latter that the description refers.
In fastening devices with pumping means incorporated in the boot, the bladder member is directly connected to the pumping means by way of an air delivery valve. This solution considerably limits the designer, in that the configuration and positioning of the bladder member is a direct function of the point in which the pumping means are to be positioned on the shell.
The solution is obviously a source of numerous drawbacks and serious limitations, in that sometimes the most comfortable and handy positioning for the pumping means corresponds to the configuration and position of the bladder member.
