Sports shoe with strong grip yet lightweight sole - has evenly closely spaced projections covering practically front tread area

摘要

The outer sole which is associated with the shoe upper has a thin-walled sheet metal part (6) which has several moulded-on projections (7) spread evenly and at the same height close together over the entire surface. This plate part (6) covers more or less the entire tread and/or rolling surface of the front sole and is connected by an adhesive to the insole (5) or to an intermediate sole. There is now always a sufficient number of projections engaging with the track whatever the position of the shoe, ie during curved running or at the start.
