<p>The football boot upper has friction surface parts (4) at least one of which is on the inside and one on the outside of the shoe. The friction parts (4) have a surface structure (3). The structured surface consists of several projections or pieces standing up from the boot, which are at least on the toe. Each projection has at least two parallel surfaces, or, pref., two surfaces at an angle to one another. The free ends or edges of the projections lead into a curved part forming a rounded cup or end. The projections can be in the form of ridges, of triangular, trapezoid, square, oblong or other cross-section, or can be pyramid, dice or parallelepiped shape.</p> |
