Contrary to the myth that youth skates do not need to be profiled or radiused, just the opposite is true. I recommend all youths learn to skate with a properly radius and pitched skate. No sense developing bad habits/body stance when you are young, it will haunt you later in life. Youths learn easy, bad habits as well. I can't even count the number of testimonials from parents who noticed drastic improvements after a PROPER radius/pitch was put on their child's skates. I won't even go into proper matching of left/right radius's. The thing is, until you've seen how a kid skates on non-profiled skates, you can't know what the proper profile will be. It would be foolish for parents to be profiling and reprofiling their 7 years olds skates trying to find the right combination. It's better to leave the skates unprofiled until tendencies can be identified. Two things. Most skate pairs the radius is not matched between left and right. So, even if you do not know the skater at all, the blades should be matched. Second, the skater can be properly evaluated through a series of questions, both from the parents and the skater themselves. A good radius technician should be able to "ballpark" a good starting point, and them just have to make minor adjustments after recieving feedback.
