Why We Custom Fit and Rivet Carbon Fibre Reinforcement in Our Skate Conversions

If you've followed our custom skate builds, you'll have seen us talk regularly about carbon fibre reinforcement. For some ice hockey skate to quad roller skate conversions, reinforcing the sole isn't simply a nice optional extra. It's an important part of creating a strong, properly supported platform for the new roller skate plate.
But there's another part of the process that deserves explaining. How that carbon reinforcement is actually fitted matters too. At Pabloskates, we don't simply drop a pre-cut piece of carbon fibre into the bottom of a boot, drill through it for the mounting bolts and call the skate reinforced. Our carbon strengthening plates are custom fitted to the individual boots, shaped to follow their internal profile and then properly riveted into position. It takes considerably longer. But there's a reason we do it.
What Happens When You Remove an Ice Skate Blade Holder?
An ice hockey skate isn't simply a boot sitting on top of a blade. The blade holder forms part of the structure underneath the boot. It's attached across a large area of the outer sole using multiple (12+) rivets, helping support and reinforce the bottom of the skate. When we convert an ice hockey skate into a quad roller skate, that entire structure is removed.
We're then asking the sole to do something it was never originally designed to do. Instead of spreading loads through a large hockey blade holder, we're mounting a roller skate plate underneath it. Depending on the construction of the boot, simply bolting that new plate onto the existing sole isn't always the best solution. That's where carbon fibre reinforcement comes in.
Why Carbon Fibre?
Carbon fibre is incredibly useful for skate conversions because it combines high stiffness with very little weight. A correctly fitted carbon strengthening plate helps distribute the loads created by the roller skate plate across a much larger area of the boot. It also creates a much stronger mounting structure than relying on a relatively thin or flexible original inner/outer soles. But simply having a piece of carbon fibre inside the skate doesn't automatically mean the job has been done properly. Fit is just as important as material.
Why We Don't Use One-Size-Fits-All Carbon Plates
Look inside several different hockey boots and you'll quickly discover something:
They're not flat. And they're certainly not all the same. The internal profile changes between manufacturers, models and sizes. Heel shapes differ. Sole contours differ. The transition through the arch differs. Even two boots that look broadly similar from the outside can have very different profiles internally. So why would we expect the same generic strengthening plate to fit all of them properly?
We don't! At Pabloskates, each carbon strengthening plate is custom fitted to the individual boot. We shape and adjust the reinforcement so it sits correctly within the particular skate we're working on. That means more measuring, more fitting and more time at the workbench.
But we're building custom skates, not assembling something on a production line.
Why Do We Rivet the Carbon Plates?
This is probably the biggest difference between our method and simply dropping a strengthening plate inside the boot. We rivet them into position, and there are two important reasons why.
1. To Pull the Carbon Plate Into the Contour of the Boot
A hockey boot doesn't have a perfectly flat internal sole. If you simply place a stiff carbon plate inside a contoured boot, the two surfaces won't necessarily sit tightly against one another across their entire area. There can be gaps between the carbon and the structure underneath. By riveting the carbon strengthening plate into position, we're able to pull it tightly against the internal contour of the boot, helping the reinforcement follow its shape rather than simply sitting loosely on top of it. This integrates the carbon plate much more effectively into the structure of the skate.
2. To Secure the Outer Plastic Sole Back to the Boot
This is just as important. Before the conversion, the original ice blade holder wasn't simply there to hold the blade. It was riveted through the bottom of the skate and, in doing so, helped clamp the outer plastic sole securely to the internal structure of the boot.
When we remove the blade holder, we also remove all of those original rivets.
That means we've removed part of what was physically holding the bottom of the boot together. By riveting our carbon strengthening plate into position, we're recreating that mechanical connection. The new rivets pass through the structure of the boot and secure the outer plastic sole back against the inside of the skate, much like the original blade holder and its rivets did before we removed them.
So the rivets are doing two jobs at once:
They're pulling the carbon reinforcement tightly into the contour of the boot, while also mechanically securing the outer sole back to the internal structure of the skate.
That's why we don't consider simply dropping an off-the-shelf carbon plate inside a boot to be equivalent. The carbon itself is only one part of the reinforcement. How it's fitted, shaped and mechanically secured is what allows it to become part of the structure of the finished skate.
A Reinforcement Plate Shouldn't Just Be a Big Washer
There's a temptation to think of internal strengthening plates as little more than oversized washers. Put something stiff inside the boot, run the mounting bolts through it and tighten everything together. Technically, you've added reinforcement. But that's not what we're trying to achieve. We want the carbon plate to work with the structure of the boot, not simply sit on top of it. That's why contouring and riveting matter. The closer the reinforcement follows the internal profile of the skate, the better we're able to spread loads across the sole rather than concentrating them around individual mounting points. It's a small detail when you're looking at the finished skate. Structurally, it's anything but.
Carbon Fibre Inside, Roller Skate Plate Outside
Once the internal reinforcement has been properly fitted and riveted, we can turn our attention to the hardware underneath. The roller skate plate is mounted externally, creating a reinforced sandwich:
Carbon strengthening plate → original boot sole → roller skate plate
The mounting hardware passes through the reinforced structure rather than relying solely on the original skate sole. This is particularly useful on boots where the original internal construction simply isn't substantial enough for us to be happy mounting a quad plate directly to it. The finished result is strong without adding excessive bulk or unnecessary weight.
Not Every Skate Needs Carbon Reinforcement
It's important to make this distinction. We don't automatically fit carbon fibre reinforcement to every skate we convert. Different boots use different sole constructions.
Some already provide an excellent foundation for mounting a roller skate plate and don't need additional reinforcement. Others benefit considerably from it. Part of doing a custom conversion properly is inspecting the individual boot and deciding what it actually requires.
Adding components simply because they're available isn't custom building. Neither is leaving them out simply because it makes the job quicker. We use reinforcement where we believe the construction of the skate requires it.
Why Not Just Glue Them?
Adhesive can certainly bond two materials together, but that's not the job we're asking our rivets to perform. We want a positive mechanical fixing that physically pulls the carbon reinforcement against the contour of the boot. Riveting gives us that. It also means we're not relying solely on an adhesive bond between two very different materials inside an environment subjected to repeated movement, vibration, temperature changes and skating loads. For the way we build our reinforced conversions, riveting is simply the method we prefer.
The Work You Don't See
When you look at a finished custom quad conversion, the obvious components get most of the attention. The boots. The plates. The wheels. The toe stops. But some of the most important work we've done is hidden underneath the footbed. By the time the skate leaves our workshop, you may barely see the carbon reinforcement at all.
That's fine. It isn't there to look impressive. It's there to do a job.
Custom-Fit. Carbon Reinforced. Properly Riveted.
That's ultimately our approach. We don't buy a stack of generic carbon plates, drop one into every boot and call it a premium conversion. Where carbon reinforcement is required, we take the time to fit it properly. Every strengthening plate is custom fitted to the individual boot. It's shaped to follow the internal profile. It's properly riveted into position. And it's installed to create a strong foundation before the new roller skate plate is mounted underneath. Does that take longer? Absolutely. Does it involve considerably more work than dropping an off-the-shelf plate inside the skate? Yes. But that's the difference between something that's been assembled as quickly as possible and something that's been individually custom built.
At Pabloskates, we'd rather spend the extra time doing it properly. Because when you're investing in a premium pair of custom quad roller skates, the quality of the work you can't see matters just as much as the parts you can. 🛼🔥
