While parents enjoy the great value for money, the kids get a fantastic skate with high quality and strong performance with the Marlee Pro. The combination of K2 Original SoftBoot and K2 Speed Lacing System ensures a perfect fit. The skates are adjustable by up to five shoe sizes, so that a child can use them for longer than one season. — K2 revolutionised the inline skate industry in 1994 by introducing the first softboot inline skates. Over 25 years later and now developed 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 is still the foundation of the K2 Skate range.
