K2 FIT 80 PRO 2022 Inline Skates K2 FIT 80 PRO 2022 Inline Skates The Stability Plus cuff provides, as the name suggests, maximum stability, which you will appreciate during fast and agile skating. At the same time, it doesn't weigh you down or pinch you, and it's the epitome of comfort. Additionally, the model is made with Softboot technology, patented by K2. This makes the shoe soft, non-chafing, and even breathable. Comfort and a lack of abrasions and discomfort caused by sweat are out of the question. The frame has been integrated with the shell, creating a single, cohesive whole. This affects vibration absorption and, in turn, stability and a smooth ride.

The model has 80A wheels - durable, but perfect for outdoor use. Thanks to their properties, they absorb bumps and make skating hassle-free. The Stability Plus shell - a lighter version of Enhanced Stability technology - ensures extraordinary stability while maintaining low weight.  Your skating will be above all safe.

ABEC-5 bearings ABEC-5 bearings  are a simple, proven bearing design that guarantees high durability and maintenance-free operation.. What is the ABEC standard? ABEC is a set of tolerance standards for the production of ball bearings. They were developed by the American Bearing Manufacturers Association (ABMA). Five tolerance classes have been distinguished: 1, 3, 5, 7, and 9 (from largest to smallest tolerance). This means that the higher the number, the greater the precision of the bearing. Individual bearing parameters are achieved first by segregating the balls, inner and outer rings, and finally using a lubricant. In fact, it's difficult to say that an ABEC 9 bearing is generally better than one with the number 5. An ABEC5 bearing was created with a specific application in a given roller skate model in mind (usually recreational skating), while type 3 bearings, for example, are primarily offered in children's roller skates. ABEC5 is a proposition for beginner skaters who value durability over speed. ABEC7 is the perfect balance between durability and relatively high speed. ABEC9 bearings are almost the highest technological level, are intended for the highest models and are usually chosen by people who value impeccable quality.   Size converter: EURO SIZEINSERT LENGTH [CM]US SIZE 36.5 23 5 38 24 6 39 24.5 6.5 39.5 25 7 40 25.5 7.5 40.5 25.5 7.5 41.5 26.5 8.5 42 27 9 42.5 27.5 9.5 43.5 28 10 44 28.5 10.5 44.5 29 11 45 29.5 11.5 46 30 12 47 30.5 12.5 48 31 13 49 32 14 Additional Materials Manufacturer's website K2 Catalog YouTube Channel
