The CCM Super Tacks 9355 have a new ergonomic “boot-shaping” system that ensures a good fit and durability. The sturdy core ensures excellent skating performance. The fit is comfortable with high resistance to wear. The 7mm tongue is made of felt and has extra foam for comfort and protection. The CCM Speedblade is not replaceable and has a pre-sharpened stainless steel blade with a raised holder for a greater angle of attack.
