Definitions

  • the invention is directed to a footwear system comprising footwear with a grip unit that is adapted to be replaceable attached to the underside of the footwear.
  • the lower wear-surface of the footwear is made of a material that provides friction and the wear-surface is also often provided with grooves.
  • the wear-surface of the sole of work shoes, boots and high boots is provided with various kinds of grooves or patterns that give an improved grip towards the ground.
  • the patent document US 3 170 251 (Patrick) describes a shoe with a sole who's wear- surface has been provided with rigidly mounted steel studs. Sharp aggressive grip arrangements such as the steel studs in Patrick provide a good grip with respect to slippery grounds. At the same time they have a disadvantage when the footwear is used on sensitive grounds, e.g. indoors on floors made of wood or stone or on other sensitive material that can be damaged by sharp objects. The shoe that is proposed in Patrick must therefore often be supplemented with another shoe that is adapted to be used on more sensitive grounds.
  • the patent document US 5 813 143 (Bell) describes a solution that at least partly sets aside the need for two pair of shoes.
  • Bell presents footwear with a grip arrangement that is arranged towards the wear-surface by means of a front clasp arrangement that attaches around the toe of the footwear, and a rear clasp that attaches around the heel of the foot wear.
  • the grip arrangement in Bell is thus stabilized with respect to the wear- surface by means of a front and a rear clasp arrangement.
  • this gives a clumsy and inexact stabilizing of the grip arrangement.
  • the grip arrangement in Bell is covering most parts of the wear-surface of the sole and thus also possible grooves or patterns that have been arranged in the wear-surface to provide a grip towards the ground.
  • the grip provided by the grip arrangement in Bell receives no or very little support from the regular grip of the wear-surface of the sole. Rather, the grip arrangement in Bell replaces the regular wear-surface, instead of supplementing and reinforcing the grip from the regular wear-surface.
  • the present invention is directed to solve at least one of the problems indicated above as occurring in previously known systems comprising footwear with a grip arrangement.
  • a footwear system comprising a footwear with an upper part that is arranged to operatively at least partly surround and retain the foot of a wearer (i.e. an user) of the system; and an at least partly flexible lower part with an outer sole that is provided with a groove pattern that is adapted to interact with a transport ground.
  • the footwear comprises a grip unit that is adapted to be detachably arranged in the groove pattern of the lower part so that a grip system of the grip unit provides additional grip towards the transport ground.

  • a fourth aspect of the footwear system comprising the features of the first aspect is characterized in that said groove pattern is divided in at least two separate groove groups.
