Definitions

• the present invention relates to a shoe with a central closure according to the preamble of claim 1.
• Such a shoe is known from DE-A-23 41 658.
• a central locking device in the form of a rotatable toggle on a tongue-like center shaft of a ski boot which is articulatedly connected to the front shoe for easy entry.
• a central locking device runs both upwards and downwards, a tension cable, essentially transversely to the center shaft.
• This tensioning rope forms a loop on the outside and is attached to the center shaft at the same height as the first loop after transverse return through the center shaft and after formation of a further loop on the other side edge of the center shaft.
• the loops lying opposite one another are in the area of the foot kick at the end of the instep, ie in the joint at the transition to the lower leg.
• the other two loops are provided in the area of the ball of the big toe or the base of the toe joint.
• Hooks are formed on the shaft material of the ski boot. In the position of the middle shaft folded towards the shaft, the loops are placed over the hooks and are turned by rotating the toggle over a rope pulley coupled to it
• the present invention is intended to achieve the object of designing a shoe with a central closure of the type mentioned in such a way that its use for shoes with a shaft material which is flexible in relation to tensile stresses in the closing area or with several flexible shaft materials, in particular for sports , Leisure or rehabilitation shoes, is made possible, that is to say with shoes that do not have dimensionally stable, shell-shaped shaft parts.
• a good adaptation of the shoe to the foot, especially in the instep area should be made possible, so that despite the foot being well fixed in the shoe, the mobility of the foot in the area of the basic toe joints as well as in the area of the upper and lower ankle joint is not restricted .
• the configuration according to the invention means that the shoe remains flexible in the area of the basic toe joints and the Tongue, especially its middle part, can adapt well to the instep shape, ie to the instep arch of the foot, over the entire length of the instep due to the soft, elastic design. Since the holding plate for the central closure does not completely cover the instep length, but rather a lower part of the tongue remains free and thus elastic, the mobility of the foot in the area of the basic toe joints, which is important for shoes that are not alpine ski shoes, is certain ⁇ asked.
