The Brand

Trail.nl started in 2013 as a small webshop for obstacle runners and mud runners. What began as a passion project quickly grew into a dedicated trail running destination, with a full online store and a physical trail shop in Amsterdam.

Trail.nl is built by trail runners, for trail runners. The team lives the sport, from local trail events to long ultras in the mountains. That passion shapes how they advise customers and why fit matters so much in their assortment.

The Challenge

Trail running shoes are unforgiving when the fit is wrong.

Customers often come in with strong assumptions about their feet. Wide, narrow, problem feet, special cases. Online, that uncertainty only grows. Guessing leads to hesitation, wrong purchases, and unnecessary returns.

Trail.nl wanted a way to give customers more certainty about fit, both online and in the store, without losing the personal, expert feel they are known for.

The Solution

Trail.nl introduced Volumental 3D foot scanning as part of their sizing and fit experience.

The scanner gives customers a clear, modern way to understand their feet and helps staff explain fit differences beyond just length or width. The same insights can then be used online, creating a consistent experience across channels.

As Trail.nl puts it:

“The combination of online and offline is really strong. It feels modern and up to date. This way we can support customers with the right size and fit, both in-store and online.”

What customers notice

The impact shows up immediately on the shop floor.

“Customers think it’s a great device. A 3D scan feels much more modern than old-school methods. When you explain it, everyone understands it and feels more confident about the shoes you recommend.” 

Instead of relying on gut feeling or habits, customers get confirmation. That confidence makes choosing easier and conversations more concrete.

A moment that says it all..

One customer walked into the store and said:

“I have thick hobbit feet. I always need wide shoes.”

The scan told a different story. Not wide feet, but a very high instep.

With that insight, the team recommended a different shoe than the customer usually bought. The result was a noticeably better fit than he had experienced before.

Customer happy. Team happy.

Why it works for Trail Running

Trail running fit is about more than size labels. Small differences in volume, instep height, and shape matter over long distances and technical terrain. Volumental helps Trail.nl move beyond assumptions and guide customers with clarity.

Better conversations. Better choices. Better runs.

Takeaway for Specialty Outdoor Retailers

If your customers guess their fit, you pay for it later in returns, frustration, and lost trust. Volumental replaces guesswork with understanding, helping retailers like Trail.nl support confident decisions, online and in-store.
