Proper skates in good condition is essential. Skates should fit, provide appropriate support, be laced properly, have a good quality blade, be protected with guards when being worn off the ice and be professionally sharpened periodically after approximately every 20 hours of use but this is by no means a hard and fast rule. ( remember that new skates are typically need to be sharpened )
Skates should fit like shoes allowing no more than about half a size for foot growth. Take out the insole and place your child’s foot on the insole and there should be about the width of a pencil from the big toe to the end of the insole.
