Shoe, especially sports shoe, comprising a shoe upper and a sole which is connected with the shoe upper, wherein the shoe upper comprises a knitted structure which at least partially surrounds a foot of a wearer during intended use of the shoe, wherein the knitted structure comprises a first set of first openings arranged side by side along a longitudinal extension of the shoe upper at a lateral side of the shoe upper and a second set of first openings arranged side by side along the longitudinal extension of the shoe upper at a medial side of the shoe upper, wherein both sets of first openings (5, 6) are arranged in a defined first height level of the shoe upper measured from the bottom of the sole, wherein the knitted structure comprises a first set of second openings arranged side by side along the longitudinal extension of the shoe upper at the lateral side of the shoe upper and a second set of second openings arranged side by side along the longitudinal extension of the shoe upper at the medial side of the shoe upper, wherein both sets of second openings (8, 9) are arranged in a defined second height level of the shoe upper measured from the bottom of the sole, wherein the second height level is different from the first height level, wherein the openings (5, 6, 8, 9, 11, 12) are adapted to thread a lace through the same and wherein the shoe upper comprises a reinforced structure which encloses at least a part of the openings (5, 6, 8, 9, 11, 12), characterized in that a semi-permeable membrane is arranged between the foot of the wearer and the knitted structure which covers the openings (5, 6, 8, 9) of the knitted structure, wherein the reinforced structure is realized by a knitted structure which is added to the knitted base material of the shoe upper, wherein the knitted reinforced structure has a higher density of meshes than the knitted base material of the shoe upper and/or additional meshes which are added to the meshes of the knitted base material of the shoe upper, so that the knitted base material of the shoe upper has a base thickness (t) and that the reinforced structure has an increased thickness, and wherein the increased thickness is arranged along the circumference of an opening (5, 6, 8, 9, 11, 12). wherein the knitted structure comprises a first set of first openings arranged side by side along a longitudinal extension of the shoe upper at a lateral side of the shoe upper and a second set of first openings arranged side by side along the longitudinal extension of the shoe upper at a medial side of the shoe upper, wherein both sets of first openings (5, 6) are arranged in a defined first height level of the shoe upper measured from the bottom of the sole, wherein the knitted structure comprises a first set of second openings arranged side by side along the longitudinal extension of the shoe upper at the lateral side of the shoe upper and a second set of second openings arranged side by side along the longitudinal extension of the shoe upper at the medial side of the shoe upper, wherein both sets of second openings (8, 9) are arranged in a defined second height level of the shoe upper measured from the bottom of the sole, wherein the second height level is different from the first height level, wherein the openings (5, 6, 8, 9, 11, 12) are adapted to thread a lace through the same and wherein the shoe upper comprises a reinforced structure which encloses at least a part of the openings (5, 6, 8, 9, 11, 12), characterized in that a semi-permeable membrane is arranged between the foot of the wearer and the knitted structure which covers the openings (5, 6, 8, 9) of the knitted structure, wherein the reinforced structure is realized by a knitted structure which is added to the knitted base material of the shoe upper, wherein the knitted reinforced structure has a higher density of meshes than the knitted base material of the shoe upper and/or additional meshes which are added to the meshes of the knitted base material of the shoe upper, so that the knitted base material of the shoe upper has a base thickness (t) and that the reinforced structure has an increased thickness, and wherein the increased thickness is arranged along the circumference of an opening (5, 6, 8, 9, 11, 12).
