It was developed with the aim of creating a system that does not require a complex and cost-intensive grinding process, but still offers excellent gliding properties. The basic idea behind the T-Blades is the easy and quick replacement of the replacement blade as soon as the tread or edges of the blade are worn. This replacement works in a similar way to the razor principle: when the blade is worn out, it is replaced by a new one. The interchangeable blades are made almost entirely of plastic and are provided with a thin metal band that forms the tread. In addition to the interchangeable blades (runner), the T-Blade system also consists of the skidden holder and a stabilizer that is used to attach the runner. Features:Area of use: Leisure, Ice hockey, HobbyOuter material: Durable nylon fabricTongue: More comfort due to extremely soft felt tongueLining: Breathable special liningHolder: T-Blade blackStabilizer: T-Blade Neon yellowRunner: Medium blackClip: Neon yellowWidth: WIDE (Regular) Sizing:In order to be able to better determine the sizes, we have measured the insoles (from edge to edge) of all Graf 103 skates.
