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 7
The ABEC classification stands for Annular Bearing Engineers Committee and classifies how finely the rolling elements (the balls in the bearings) are machined. The higher the ABEC level, the more precise the production and the better the wheels turn. ABEC 7 ball bearings have even running characteristics such as smooth running and easy turning of the wheels. This means that power can be transferred efficiently when riding. However, it should be noted that the smooth running of a ball bearing is also influenced by other factors, such as the materials used for the various components of a ball bearing and the choice of lubricant.
