Overview
The Kizer Clipper Buckle Sets are sold as a pair, with mounting hardware, in either black or white. They are plastic buckles that fit the many USD skates and likely other brands also. They feature a locking buckle that stays in place even during a fall.
The different lengths (shown when available) are 18cm, 21cm, and 23cm. All would work for most skates, but depending on preference one can order long or short and even cut them down to size later. For a generalization on sizing, smaller boots sized 8 or smaller may choose the 18cm, sizes 9 and 10 the 21cm, and larger skate sizes the 23cm.
