Abstract: The invention provides a shoe (1) with a sole providing a dynamic foot arch support, the shoe comprising a rubber outsole (9) and an upper (10), the shoe further comprises a midsole (2), the midsole comprising a harder elastic material (4), a softer elastic material (5), wherein the harder elastic material has elastic hardness in a range 1.3 to 3 times higher than the softer elastic material.

Abstract: The invention provides a shoe with a sole providing a dynamic heel support, the shoe comprising a rubber outsole, a midsole comprising a harder elastic material, a softer elastic material, and at least one insert having a higher elastic hardness than the harder elastic material and the softer elastic material, and a higher resistance against bending, wherein the harder elastic material has elastic hardness in a range 1.3 to 3 times higher than the softer elastic material. The shoe is is distinguished in that the harder elastic material is arranged in a band inside the periphery along the sides and heel of the midsole, wherein the softer elastic material is arranged in the midsole inside the band of the harder elastic material, wherein the at least one insert is arranged within the softer elastic material, at least in the heel part of the midsole, and wherein the thickness of the softer elastic material above the insert in the heel part of the midsole is at least 0.

Abstract: Shoe comprising a sole and at least a part of an upper leather fastened to the sole, distinctive in that the shoe is constructed or adapted so that the resultant force vertically up from the base during walking, in the main, moves along a certain line or path, called SGL (sensory gait line) as the line, for the right foot seen from above, starts from the back, tilting from the outside at the setting down of the heel, the line goes forwards and turns outwards so that it goes under the middle of the calcaneus (heel bone), from where the line further forwards has a shape as an extended S that runs out between the first and the second toe.
