Everything about cuffs

Short answer:

The cuff is the part of the skate that can be flexed forward. There are a few things that can be customized on your cuff like the flaps. When replacing a cuff we generally advice to take the original model.

The Importance of a cuff in inline skating

The cuff is perhaps the most essential piece of hardware in inline skating. Without having a part of the skate that flexes forward the skate will be too stiff. If you make a skate without a cuff entirely, like some speed skates have, then you will not have the stability to control your self in difficult situations like breaking and steering techniques

 

V-Cut or Not?

The V-cut is a specific notch at the back of the cuff that changes how a skate flexes backward. While some skaters prefer it, a V-cut is often a "workaround" for a cuff that wasn't designed with proper backward flex from the start. If a cuff is designed correctly, a V-cut isn't strictly necessary for performance. However, the V-cut is particularly beneficial for women, as they typically have a lower calf muscle than men, and the notch provides a more comfortable fit for their anatomy.

 

Cuff Flaps

Underneath the buckle sits the cuff flaps. On models like the FR, Next, and Aeon, the cuff "flaps" are often too long. Cutting these down allows you to tighten the skate properly without the plastic parts overlapping. These flaps make the skate stiffer in their forward and in their sideways flex. They also sometimes make it harder to close a skate properly.

 

What Cuffs Fit on What Models?

Unfortunately, there are no universal cuff standards, so skaters are often limited to aftermarket parts from their own brand. However, due to shared histories, some systems are compatible:
