The Powerslide Phuzion Radon Teal 90 inline skates are fitness inline skates for women that are the epitome of comfort. Built on a strong and rigid shell, as well as a specially reinforced upper with glass fiber. Combined with the TRINITY mounting system, they provide an incredible sense of stability while inline skating. They significantly improve power transfer and reduce vibrations generated while skating on uneven surfaces. Riders also benefit from a comfortable, low center of gravity that is especially beneficial for a better sense of balance. The new Powerknit upper with TPU reinforcements provides precise support. The Powerslide Elite 4x80-243mm die-cast aluminum frame is lightweight and stiff. The incredibly comfortable dual-density foam inner liner with additional heel lock guarantees the most comfortable and efficient ride possible all day long. The heel position is raised by 2 mm. At the same time, it forces the skater to lean more and reduces the possibility of falling backwards, which is extremely important especially for beginners. This is an extremely agile skate for women, which rolls smoothly and quickly thanks to the Powerslide Infinity 4x90mm wheels and the highest Wicked ABEC 5 bearings. The set includes an effective Powerslide HABS brake. Tune in for a smooth ride The outer shoe has been specially sewn with durable synthetic material. It provides optimal foot support. The chassis is a classic 4x90 set. The base of the skates itself has been slightly widened to allow for more room to maneuver to adjust the rail sideways. The Phuzion Radon collection is characterized by a subtle look and high quality. The fiberglass-reinforced shell has an attached liner that helps maintain a low profile of the skates. The model uses 4 x 90mm wheels on the Trinity rail. This is another revolution that had to come after the introduction of much larger wheels. Mounting the TRINITY rail means lowered center of gravity regardless of the number or size of wheels, increased stability and better power transfer, improved sense of balance and control.

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 the largest to the smallest tolerance). This means that the higher the number, the more precisely the bearing is made. The individual bearing parameters are achieved first by segregating the balls, inner and outer rings, and finally by using a lubricant. In principle, it is difficult to say that the ABEC 9 bearing is generally better than the one with the number 5. The ABEC5 bearing was created with a specific application in a given model of roller skates in mind (usually recreational skating), and for example type 3 bearings are mainly offered in children's roller skates, then ABEC5 is a proposal for beginner skaters who value durability much more than speed. ABEC7 is the perfect optimum between durability and relatively high speed. ABEC9 bearings are almost the highest technological shelf, they are intended for the highest models and are usually chosen by people who value impeccable quality. Powerslide technologies: Elite Aluminum - The Elite Aluminum runner is made of a single piece of aluminum, which means there are no screws or other elements that can increase the weight or reduce the parameters. This construction means less weight, greater stiffness and lower height than in the case of classic two-element solutions. Phuzion Innersole - The special construction of the bottom of the inner shoe provides ventilation and more space around the toes. Thanks to the use of EVA foam with increased density, it improves the stability of the foot in the shoe and allows for a perfectly anatomical fit. Thanks to the use of Biolast II technology, the entire inner shoe is shaped in 3D already at the first stages of production, and the use of vibration-absorbing gel allows you to achieve previously unavailable fit, stability and uncompromising comfort. X-Torsion Bar System X-shaped reinforcement in the lower part of the shell increases its stiffness and improves energy transfer, which is extremely important at higher speeds. This technology is widely used in racing models, where it has been very well received. Hinge Screw The connection between the upper and the lower part of the shell is a place where very high stresses occur, the quality of this connection is also crucial for lateral stability. The rivets used in Powerslide skates have been designed with a large reserve of strength, so you can squeeze 100% of the skate's capabilities and not worry about whether it will withstand such treatment. Heel Retention System This system increases heel stability by adjusting the width of the shell. This solution works perfectly with the new protective panels placed in the inner shoe and other systems that increase comfort and stability.
