Shoe structure

A shoe structure comprising:

• an upper with a flexible body defining a cavity with an opening to receive the user's foot and a sole body with a midsole with an upper surface associated with the upper to support the sole of the user's foot,
• wherein the shoe structure comprises an elastically deformable support element, fixed underneath the lower part of the upper facing the ground away from the opening building part of the sole body and
• a traction element, configured in a grid pattern and connected at the bottom surface of the sole body, the traction element comprising a main centred non-slip surface fixed underneath the centre of the sole body and edge sections, at least partly wrapped around the outer edge of the sole body and the lower edge of the upper,
• wherein the grid-like traction element is adapted to contain the deformation of the upper and sole body during use of the shoe structure, cooperating with the resiliently deformable resilient support element to provide the user's foot with an elastic return of the energy stored during use of the shoe structure resulting from the elastic deformation of the grid-like traction element and the support element.
