The F.I.T 84 Speed Alu is designed for men seeking an outdoor workout that challenges them while being gentle on the joints. The skate features an aluminum frame for a stable riding experience. With the K2 Original Softboot, ILQ-5 bearings, and 84 mm wheels, the inline skater enjoys comfort, speed, and an enjoyable outdoor workout. K2 revolutionized the inline skate industry in 1994 with the introduction of the first softboot inline skates. Over 25 years later, now evolved into a complete range of inline skates for women, men, and children for all purposes—from family fun to daily fitness and professional competitions—the softboot design remains the foundation of K2 Skates' product line.
