PerfittSize Expands Across Mizuno EMEA: Bringing AI-Powered Fit Confidence to More Online Shoppers

PerfittSize Expands Across Mizuno EMEA After Proven Results in Sales, Returns, and User Growth

Online footwear shopping continues to grow, but one challenge remains the same:

Customers still hesitate when they are not sure which size will fit.

For global footwear brands, this hesitation is not just a UX issue. It directly affects sales conversion, return rates, customer satisfaction, and operational efficiency.

That is why Mizuno EMEA first adopted PerfittSize, Perfitt’s AI-powered shoe size recommendation solution, across selected European markets and products.

The results were clear.

After the initial rollout, PerfittSize showed measurable business impact across online sales, return reduction, and customer engagement. Based on this performance, Mizuno EMEA has now expanded PerfittSize from 3 countries to 6 countries and from approximately 100 SKUs to 400 SKUs.

The expansion also delivered immediate user growth:
in the first month after expansion, the number of new monthly users increased by 6x.

For Perfitt, this is an important milestone. It proves that AI-powered fit technology can go beyond size recommendation and become a scalable growth engine for global footwear e-commerce.

From 3 Countries and 100 SKUs to 6 Countries and 400 SKUs

PerfittSize was first implemented across Mizuno EMEA in selected markets, including Germany, France, and the Netherlands, with around 100 running footwear SKUs.

This initial phase was designed to validate whether AI fit recommendation could create measurable value in real e-commerce environments.

The outcome showed strong potential.

During the initial rollout, PerfittSize helped Mizuno EMEA achieve:

+87% online sales uplift in implemented regions
+20% higher sales volume compared with non-implemented regions
up to 28% reduction in return rate among key products and markets
25% reduction in bracketing purchases, where customers order multiple sizes and return the ones that do not fit

These results showed that size recommendation is not just a support feature. It can directly influence how customers make purchase decisions, how often they return products, and how confidently they shop online.

Based on this performance, Mizuno EMEA expanded PerfittSize to additional markets, including the United Kingdom, Spain, and Italy.

The rollout now covers 6 European countries and approximately 400 SKUs, expanding beyond the initial product scope.

6x Growth in New Monthly Users After Expansion

The strongest signal came immediately after the expansion.

Within the first month after expanding the number of countries and SKUs, PerfittSize recorded a 6x increase in new monthly users.

This shows two important things.

First, customers actively engage with fit recommendation when it is available at the right moment in the shopping journey.

Second, expanding coverage across more products and markets can create a powerful network effect. The more SKUs and countries PerfittSize supports, the more customers can experience personalized fit recommendations, and the more fit data the brand can use to improve future customer experiences.

In other words, PerfittSize does not only solve a size problem on one product page.

It helps brands build a scalable fit intelligence layer across their e-commerce business.

Why These Numbers Matter

The footwear category has one of the most sensitive size and fit problems in e-commerce.

Even when customers know their usual size, the actual fit can vary by brand, model, material, width, shape, and product purpose. This is especially true for performance footwear, where fit affects not only comfort but also movement, stability, and confidence.

When customers are unsure, they hesitate.

That hesitation often leads to three outcomes:

They leave without purchasing.
They order multiple sizes.
They return the product after purchase.

Each of these outcomes creates cost for the brand.

PerfittSize helps reduce this uncertainty by combining foot measurement, shoe inner data, and AI fit intelligence. Instead of relying only on general size charts or customer reviews, PerfittSize recommends the most suitable size based on each customer’s foot profile and each product’s actual fit characteristics.

This is why the Mizuno EMEA results are meaningful.

The impact was visible not only in customer engagement, but also in business metrics:

more online sales, fewer returns, less bracketing, and faster user growth.

Fit Recommendation Is Becoming Commerce Infrastructure

A size recommendation button may look like a small feature.

But in reality, fit impacts the entire commerce funnel.

It affects whether a customer clicks “Add to Cart.”
It affects whether they complete checkout.
It affects whether they keep the product.
It affects whether they come back to buy again.

For global brands like Mizuno, this becomes even more important across multiple countries and categories.

Different markets have different customer behaviors. Different products have different fit characteristics. Different shoppers have different expectations.

A scalable AI fit solution helps brands deliver a more consistent and personalized shopping experience across markets — while also collecting valuable fit data that can support merchandising, product planning, inventory strategy, and CRM.

This is the bigger meaning behind the Mizuno EMEA expansion.

PerfittSize is not simply being added to more pages.
It is becoming part of the digital infrastructure that supports more confident footwear shopping at scale.

From Better Fit to Better Business Performance

The Mizuno EMEA case shows a clear pattern.

When customers receive better fit guidance, they are more likely to buy with confidence.
When customers buy the right size from the beginning, returns decrease.
When more products and markets are covered, more customers use the service.
When more customers use the service, the brand gains stronger data and deeper customer insight.

That is the growth loop PerfittSize is designed to create.

Better fit leads to better conversion.
Better conversion leads to higher sales.
Better size accuracy leads to fewer returns.
More usage leads to stronger data.
Stronger data leads to smarter business decisions.

This is how fit technology becomes more than a customer experience tool.

It becomes a performance driver for global footwear commerce.

These numbers show that customers want more confidence when buying footwear online — and that brands can turn fit confidence into measurable business growth.
