The CCM Tacks 9040 Skates are a great choice for the recreational or new-to-hockey player that wants a skate that is ready right out of the box. The Tacks 9040 skates come with pre-sharpened runners (or blades) so they can be taken directly to the rink or pond, unlike most of the competition. While they are not replaceable, the runners sit in SpeedBlade Pro holders that look like what the NHL Pros use. CCM new boot makes these 9040 skates more durable and more accommodating for casual skaters or anyone looking to learn how to skate.
