The SK8W8 is an adjustable skate weight used by hockey players to build speed and explosiveness.

Each SK8W8 has a high-impact nylon shell that holds up to three steel weights, each of which weighs 113 grams (four ounces). The weights can be added and removed as desired.

The SK8W8 is a training aid for all athletes training on ice skates, from hockey players, to speed skaters. It will assist in conditioning by increasing strength, muscle tone and cardiovascular endurance. The principle is simple: by adding weight to the skate, in a location that keeps the normal mechanics of skating the same, extra work is added to your training. When they are removed for a game, you will really fly!
