Inline Rollers by the company Athlopaidia. The Inline Rollers feature a series of aligned wheels located towards the center of the frame, under the boot. They increase speed more easily compared to Quad Rollers because they have a smaller friction surface with the ground, making them ideal for fast skating. High speed requires more balance and control, which is why experienced inline skaters develop techniques for speed adjustment and stopping.

These particular rollers are adjustable. The ability to adjust the size makes it easy to quickly adapt the roller to the user's foot. This way, you have the ability to find exactly the size that fits your foot, while also making them ideal for use by different people.
