They've been around for almost as long as inline skating itself. K2 skates continue to be arguably the most comfortable aggressive skates on the market. This, combined with their high quality build and engineering makes for an awesome ride. A little different to most other aggressive inline skates as a result of the cuff (ankle part) attaching to the inside of the baseplate flange (most cuffs 'overlap' rather than 'underlap'). This gives a whole different, more gradual flex on grind tricks. K2 have been producing the 'Fatty' style design since circa 1996 with the updated soulplate being introduced in 2010 (on the K2 Varsity skate). K2's engineering experience in the fields of Skiing and recreational skate manufacturing means that their finished product has that extra twist of finesse.
