Sure-Grip Super CONICAL Cushions. One of the best things you can buy for your skates. Specifically designed for use in Sure-Grip skates. Made from the best high quality high rebound urethane.
Cost is per each, buy 8 for a full skate pair. Purple 85A are the most common cushions.
Fritzy's Tip: These are not super common, and usually you need 4 conical cushions and four barrel cushions!
