When every second matters, the right gear can mean the difference between the podium and the pack. Few know this better than Diederik Hol, Owner of Cadomotus, a company born on the razor’s edge of speedskating and now redefining triathlon footwear.
“Cadomotus started in speedskating, a sport where equipment defines fractions of a second,” Hol explains. “Over time, we shifted our focus fully to triathlon, a sport that combines endurance, speed, and transitions. What inspired us was always the same: helping athletes perform better through intelligent design.”
CarbonShell™ - Power to the Pedal with Every Stroke
At the heart of Cadomotus’s innovation is the CarbonShell™ sole - a heat-moldable, shell-type construction adapted from speedskating to cycling shoes. This technology gives triathletes the edge they need: quick entry and exit in transition, combined with maximum power transfer on the bike.
“Unlike standard flat-carbon shoes, our shell construction locks the foot securely with just one BOA, a velcro strap, or sometimes no closure at all,” says Hol. “That advantage in the first transition sets the tone for the rest of the race.”
The catch? For the performance to work, the fit has to be exact.
From Trial-and-Error to Precision Fit
Before partnering with Volumental, Cadomotus relied on size charts, manual Brannock measurements, and athlete trial-and-error. “In practice, athletes often ordered multiple pairs and returned what didn’t fit,” Hol recalls. “It worked, but it was inefficient for both sides and not the best first experience with our brand.”
That changed when Cadomotus tested Volumental’s online 3D foot scanning solution.
“We tried 5 - 8 different apps before we found Volumental,” Hol says. “No other app was that simple and clear. With Volumental, customers get helpful feedback step by step, which makes it far easier to capture accurate data and make a better choice.”
Pro-Level Fit, Anywhere in the World
For Hol, the impact was clear: “It gives every triathlete, anywhere in the world, the same precision fit experience a pro might get in a bike fit studio. That democratization of precision was exactly what our customers needed.”
Athletes scan their feet at home, then use Cadomotus’s size guide - based on Volumental’s length, width, and volume scores - to select the right CarbonShell™ shoe. From there, heat-molding completes the fit.
“Our athletes don’t just get a shoe, they get a system: scan, size, mold, race,” Hol explains. “That’s what makes our approach unique in cycling and triathlon.”
Winning Margins on Race Day
Since adopting Volumental, Cadomotus has seen a drop in returns, faster purchase decisions, and stronger athlete confidence. The scan data also feeds into future product development, with real-world athlete foot shapes informing new lasts.
Hol recalls one story in particular: “An Ironman athlete told us that after scanning with Volumental and heat-molding his Chronos Aero shoes, it was the first time in ten years he raced without foot pain. That’s performance unlocked.”
Building for the Future
Volumental’s scanning technology also empowers Cadomotus dealers and bike fitters to recommend the right size even when inventory isn’t on-hand. That means fewer lost sales and a smoother customer experience.
As Hol puts it: “We’re a niche brand without shops in every town around the globe. Volumental lets us sell worldwide with confidence, without needing customers to try on shoes in a store. It’s a scalable solution that keeps fit precision at the heart of our brand.”
The Finish Line
For Hol, the lesson is simple: “3D scanning only works if it’s integrated into your product philosophy. For us, the scan selects the right size, and heat molding completes the custom fit. Without that second step, you’re only halfway there.”
By pairing Volumental’s precision with Cadomotus’s CarbonShell™ innovation, triathletes gain more than just equipment; they gain confidence, efficiency, and performance when it matters most.
