Designed for the fitness skater that demands more comes the K2 F.i.t. 84 Pro Inline Skates. The F.i.t. 84 Pro gives skaters power and transfer stability and features a stiff, durable and responsive Stamped Aluminum frame that gives skaters a solid base while housing four 84mm wheels that will provide a smooth, comfortable roll. The Speed lacing system on these skates lets you quickly fasten the skates with a single pull and the extra lacing can be rolled up and stored in the tongue. This skate is super comfortable thanks to the K2 Original softboot that provides skaters with a well-rounded skate that makes for an enjoyable experience.
