Buckle
The practical buckle on the upper ankle fixes the foot optimally in the shoe and provides sufficient stability. Depending on the shoe and foot, the ratchet can be adjusted individually.
Lacing
With classic lacing, the laces are tied by hand to form a loop. This is an advantage because the traction and pressure can individually be controlled depending on the shape of the foot. The skates with classic lacing are also particularly attractive in price.
4 Wheel
4-Wheel tracks have, like the name suggests, four wheels. The normal 4-wheel inline skates are much safer and easier to control, which is why they are particularly suitable for beginners as well as fitness and hobby skaters. However, advanced skaters can reach high speeds even on 4 wheels, for example, by choosing larger wheels and therefore experience great driving fun. The Maximum size of the rollers is noted on the skate rail.
ABEC 9
The classification ABEC stands for Annular Bearing Engineers Committee and classifies how fine the rolling bodies (the balls in the bearings) are worked out. In other words, the higher the ABEC level, the more precise the production. ABEC 9 bearings have consistent running characteristics such as good smoothness and smooth rotation of the rolls. Thus, the power can be transferred efficiently when driving. However, it should be noted that the smooth running of a bearing is also influenced by other factors - such as the materials used for the various components of a bearing, as well as by the choice of lubricant.
