The 3mm Ultrastop Shot Blocker Foam is a non-porous impact absorbing foam. It is top laminated with abrasion and cut resistant superfabric and bottom laminated with non-reusable pressure sensitive adhesive. 

One package comes with four pieces for the inside and outside of your skates. These are designed to fit skates sizes 5-12 and must be cut to the proper shape based on the template provided and your skate. 

*NOTE: Be sure to bake your skates before applying the shot blockers. Overheating the shot blockers can cause delamination or premature cracking. Not responsible for improper installation.
