Roller Blades The New Exercise Equipment

Roller blades are a variation on roller skates, with a unique and different design. In line skates, also called Roller Blades, were created based on the design of ice skates and adaptations were made. The smooth polyurethane wheels on in line skates are set in a single row underneath the boot of the skate.

Some in line skates have laces as fasteners, but the most common type of fasteners are clips. Laces are still used by some people because of the fact that they offer more precision and control, and the in line skaters who are aggressive with their movements, participate in hockey, or race actually need laces for additional control of their movements. Clip fasteners are preferred by most skaters for several reasons, including the fact that they are much easier to fasten and unfasten. The clip systems that are available today can be very sophisticated and will provide a precise fit.

The wheel frame is the actual structure that gives support to the wheels. This frame is normally made out of polycarbonate or nylon that is reinforced by glass. The lighter and stiffer the frame is, the better the performance of the skate. The frame of the skate affects the performance and the control, so it is an important aspect of the skate.

One of the most important aspects of an in line skate is the foot bed, especially when it comes to comfort. The foot bed should consist of more than just stiff cardboard, and there should be plenty of soft material under it to cushion the foot. Top of the line foot beds are usually either made from some type of biomechanical technology or they are custom molded.

The two things that affect the performance of the skate the most are the wheels and bearings. These two pieces of equipment have grading classifications that are internationally recognized, and these classifications are the best knowledge you can have when going to purchase in line skates. Avoid any wheels that are soft and cheap, as these will not roll right. The hardness of a wheel is measured by a durometer. The numbers for the durometer range anywhere from 74 to 100, and the higher that the number is, the harder that the wheel is. The most popular wheel hardness is 78A. Good bearings should be silent and spin freely. Always make sure to inspect your skates before and after each use for any problems or spots that need maintenance.
