  • the present invention relates to a sole suitable to be used for the realization of a sports footwear.
  • soles made of various materials are known.
  • thermoplastic polyurethane TPU
  • this material has a high stiffness, which in the course of sporting activity results in high stresses on the legs or joints of the user.
  • a sole used for the sporting activity of football is not necessarily suitable for use in another sport, for example for the sporting activity of cycling or running in natural outdoor environments ("trail running").
  • Each discipline determines stresses in different portions of the user's legs or joints and also requires footwear with different characteristics for the different performances to be performed.
  • Another parameter to consider is the shape of the cleats, which must also vary based on the type of terrain on which the sole is used.
  • a sole made of rigid material with cleats made of soft material is required, to best alleviate the stresses that are transmitted to the leg or joints of the user.
  • a sole made of a certain rigid material with cleats made of a soft material the two parts struggle to stay firmly connected to each other, especially if subjected to stresses and friction with the ground.
  • the main object of the present invention is therefore to provide a sole for footwear, in particular a sole for sports footwear, which is capable of improving the state of the prior art.
  • Another object of the present invention is to provide a sole for footwear that has a high degree of versatility and which can therefore be used for multiple sports activities or in different or variable conditions within the same sporting discipline.
  • Another object of the present invention is to provide a sole for footwear suitable for alleviating as much as possible the stresses transmitted to the leg or joints of the user.
