The K2 League is a semi-professional/amateur football league, below the level of the K-League in Korea, consisting of ten clubs. The season is comprised of two sections with the 10 member clubs playing each other once in each section. The two section winners then play off home and away at the end of the season to decide the league champion. In the event of the same team winning both sections, then that team is pronounced champion without the need for a play off.
The K2 league is currently a closed league, with no promotion to the K-League and no relegation out of the league. Plans are afoot however for promotion and relegation to be in place between the K2 League and the K-League in time for the 2007 season, with a possible promotion/relegation system involving a rumoured K3 division sometime in the future.
K2 believes that the growing influence of large format sporting goods retailers and retailer buying groups as well as the consolidation of certain sporting goods retailers worldwide is leading to a consolidation of sporting goods suppliers.
K2 skates are attractive and of high quality and have innovative features such as a soft mesh and leather upper designed for improved comfort, with a rigid plastic cuff for support.
K2 believes another factor in its level of inventory investment is the shift by certain of its sporting goods customers from substantial purchases of pre-season inventories to deferral of deliveries until the products' retail seasons and ordering based on rates of sale.
Kookmin Bank dropped out of the league at the end of 1984, and Hallelujah followed the season after, though the latter continue to play in the K2League.
Most of the clubs in the league are owned by major Korean corporations, with some of the corporations owning stakes in more than one side (Ulsan Hyundai Horang-i and Cheonbuk Hyundai Motors, for example).
Below the level of the K-League there is the K2League, a closed semi-professional/amateur league with twelve members, established in 2003.
