How nine Dutch stores turned shoe take-back into a customer acquisition channel.

Runnersworld piloted Utilitarian across five stores from August to December 2025. In January 2026, Runnersworld committed to twelve months of ongoing use. The programme now runs in nine stores. Totals exceed 1,000 customers and 1,500 scans with product-level data.

The partners

Three organisations, one pilot.

Runnersworld & INTERSPORT

Part of EK Netherlands. Nine stores, starting with Hoorn and Eindhoven — including the launch of The Loop circular concept store.

Retail partner

FastFeetGrinded

Recycling partner since 2016. 100,000+ pairs processed with Runnersworld. Handles collection, sorting and material recovery.

Recycling partner

Utilitarian

Consumer-facing take-back app, product-level data capture, CRM integration and recycler tracking. Poster + QR code — no IT integration.

Platform
Before the pilot

Take-back was already happening. Connection and control were missing.

Runnersworld has collected shoes with FastFeetGrinded since 2016 — an estimated 100,000+ pairs. Customers brought in old shoes, store teams boxed them, FastFeetGrinded collected them. A weight report came back. The interaction ended there.

What we changed

A poster in-store. A twenty-second interaction. Everything else stays the same.

We added a data layer to the moment that was already happening. The customer still hands in their shoes. The box still goes to FastFeetGrinded. What changed is what happens in between.

Deployment

Timeline

Live within weeks of kickoff

Hoorn and Eindhoven first, additional stores rolling out over the following weeks.

Store setup

A poster with a QR code

No hardware, no app installation, no IT integration.

Staff training

None required

Customer self-serves via their phone. Store teams continue as normal.

IT integration

None

Platform runs standalone. Dashboard + export. CRM connection available but not required.

The results

Six months. Nine stores. Measurable outcomes.

1,000+ Customers participated
1,500+ Scans with product-level data
€1–3 Cost per email vs €12–31 paid channels
5 brands ~75% of scanned shoes Product-level insight no other channel provides
Repeat visits Customers returning to collect their rewards Take-back as a reason to come back

The pilot resulted in a committed partnership for 2026, with expansion across additional stores and product categories.

Beyond the stores

Rotterdam Marathon.

The same platform that runs at a permanent retail counter works in a tent at a finish line. We proved it in April.

When April 2026
Where NN Marathon Rotterdam · Expo village
Host ASICS EMEA + FastFeetGrinded
Capture Worn racing shoes · any brand

ASICS EMEA hosted the activation at their expo stand at the marathon village. Runners brought worn racing shoes — of any brand and any condition — photographed the shoe, registered the model and condition, and left an email for a follow-up.

The activation proved a capability the permanent in-store deployments do not. A platform that runs on a customer's mobile phone, with product recognition handled on the back end, does not need fixed hardware.

Event-context take-back is a different commercial conversation. The lead arrives at peak product affinity, the venue context is unambiguous, and the activation window is bounded. Brand partners interested in event deployments can get in touch.

Value delivered

One programme. Four teams served.

Marketing

Email subscribers at €1–3 each with brand and category data attached. A new owned channel with purchase-intent signal built in. Repeat visit behaviour driven by incentive redemption.

Sustainability

Product-level take-back data structured for CSRD and EPR reporting. Auditable traceability from consumer interaction through to circular outcome.

Operations

Zero additional burden on store teams. No staff training, no new devices, no IT integration. Runs on a poster and a QR code. Customers self-serve.

Recycler · FastFeetGrinded

Product-level visibility into what's being collected — not just weight. A richer service offering for retail clients as the programme scales.

What the partners said

In their own words.

The steps were self-explanatory. Customers responded positively. They are very curious about what actually happens to the shoes.
Wim Entrepreneur, Intersport Ermelo
We even see customers coming back specifically to hand in their shoes and collect their reward — which shows the system is working very well in terms of building loyalty and repeat visits.
Rowen Slagter-Pormes Management, Runnersworld Hoorn
What makes this data valuable is not just transparency, but control. For the first time, we can link consumer returns at retail directly to operational circular outcomes.
Danny Pormes CEO, FastFeetGrinded
The combination of simplicity, customer engagement and data-driven transparency is what makes this approach stand out. This is exactly the direction our industry needs.
Ron Bruinenberg Retail & Expansion, EK Netherlands
Operational detail

The questions people ask.

What happens when the collection box is full?
The same thing that happened before — FastFeetGrinded picks it up on their regular schedule. The app runs independently of physical collection logistics. Nothing changes for store teams.
What product data is captured?
The customer selects brand and category of the product they're handing in. This gives product-level insight into what's being returned — which brands, which categories — linked to an identifiable customer.
What does the customer experience look like on mobile?
Scan the QR code, take a photo, confirm the brand, enter email. A thank-you email arrives with a discount and store link. About twenty seconds total. No app download.
What data does the marketing team get?
An email address linked to a product record — brand and category. First-party data with purchase-intent signal, captured at €1–3 per email versus €12–31 through paid channels.
Did store staff need to change anything?
No. The customer self-serves entirely. The only visible change in-store is a poster near the collection point.
What happens to the shoes after collection?
FastFeetGrinded handles sorting, processing and material recovery. Wearable pairs go to reuse markets. Non-wearable shoes are processed into granulate. Ethical processing standards are required — not optional.
What's next

Continuing with running shoes. Expanding from there.

The pilot proved the model works at store level. For 2026 the partnership continues — rolling out to additional Runnersworld and INTERSPORT stores. The infrastructure is poster-based and QR-driven, so expanding means printing more posters, not deploying more technology.

Beyond running shoes, the platform supports additional product categories including textiles and electronics. The EU Battery Regulation is also creating take-back requirements that apply across multiple retail divisions.
