CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is based upon patent application PCT/DE 2004/000023 filed Jan. 13, 2004, International Publication No. WO2004/064551. BACKGROUND OF THE INVENTION [0002] The invention relates to a sock, in particular for use in athletic activities. [0003] Human feet are often accommodated in tight shoes. This is the case in particular when the person moves quickly and a lot, e.g., in athletic activities. The tight shoes themselves result in increased perspiration on the feet. During athletic activity such a person will experience above-average perspiration. Since the risk of the development of blisters on the foot is increased due to the accumulation of perspiration in the shoe and/or sock, there have been attempts to facilitate the removable of perspiration from the shoe and/or sock. [0004] German Utility Model DE 297 15 762 U1 discloses a climate-regulating stocking, in particular for use in types of leisure activities such as jogging, inline skating, skiing or the like, having at least one integrated air channel made of a climate-regulating mesh knit fabric extending from the sole of the foot to the band at the top. The climate channel allows most of the moisture generated to evaporate by conveying the moisture of perspiration out of the tread area of the foot and into an area of the stocking where free evaporation is possible. The known climate-regulating stocking fulfills all the requirements made of it. [0005] The object of the present invention is to further improve upon the removal of moisture from the shoe. According to this invention, this object is achieved by providing at least one climate channel in the tread area. [0006] This invention creates a sock, in particular for athletic activities, which further improves upon the removal of perspiration from the shoe and/or sock. By providing a climate channel in the tread area, it is possible to promote the conveying of the moisture that occurs in the area of the sole of the foot directly out of the area of the sole of the foot via the climate channel. The moisture can then escape through ventilation holes in the shoe. [0007] In a further embodiment of this invention, the tread area of the sock has a central climate channel with additional climate channels branching off from it to the outer area of the sock. This achieves a uniform climate in the tread area. Furthermore, an equalization of pressure between the channels is achieved, resulting in a uniform removal of moisture under load. In addition, a pleasant feeling of occurrence is induced with the tread. [0008] In an embodiment of this invention, the climate channel has a bent or wavy pattern. This enlarges the effective channel length, which results in an increase in the transport capacity while also increasing the surface area available for cooling in the tread area. [0009] In another embodiment of this invention, the channels in the tread area are designed with a constriction. Due to the partial tapering of the channel path, accelerated air guidance is achieved, which in turn accelerates the removal of moisture out of the tread area and causes an increase in the cooling power in this area. [0010] In another embodiment of this invention, an air channel is provided optionally on the inside and/or outside of the leg of the sock and this air channel is connected to the climate channel in the tread area. This provides an additional path for removing perspiration from the tread area of the foot. In the case of air channels on the inside of the leg and the outside of the leg, an additional air circulation in the shoe is achieved through the connection of the air channels. [0011] In another embodiment of this invention, the sock has cushions. The cushions may be provided at different locations in the sock. They reduce skin abrasion as well as the risk of pressure points developing on the foot. [0012] The sock is advantageously equipped with an X-cross bandage. The X-cross bandage supports the ankle in the transition area between the leg and the foot. [0013] Other embodiments and improvements on this invention are described below.
