The short version
Giesswein is a €100M+ annual revenue premium wool shoe brand that experienced a significant revenue drop after the post-COVID e-commerce correction. With no clear diagnosis for the decline, DRIP conducted a Category Entry Point analysis that revealed 'Initial Quality Perception' was the top purchase driver. Over three years of testing, we generated €12.2M in additional revenue — including a single test that added €232,500/month.

02The Brand
Why Giesswein needed a sharper growth system.
Giesswein is an Austrian premium footwear brand known for its innovative use of Merino wool in shoe construction. With over €100M in annual revenue, the brand has a strong DTC presence across European markets, selling directly through their own online shop.
The brand's unique selling proposition — sustainable, high-quality wool shoes that combine comfort with eco-consciousness — resonated strongly during the COVID e-commerce boom. But when the post-COVID correction hit, Giesswein experienced a meaningful revenue decline with no clear understanding of why.
Live shop context
Giesswein had a premium product story. The site had to make that quality tangible fast.
The live storefront already carries wool, comfort, and outdoor cues. The research showed the buying system needed stronger proof around material quality, durability, returns, and purchase confidence.

03The Challenge
The conversion problem behind the headline.
After the post-COVID e-commerce normalization, Giesswein's online revenue dropped significantly. The team didn't have a clear diagnosis: Was it a market shift? A product issue? A site experience problem? Without data-driven insights, they couldn't determine what had changed or how to fix it.
The brand was making decisions based on internal assumptions about what customers valued, but those assumptions hadn't been validated against actual customer behavior. The gap between what Giesswein thought customers cared about and what actually drove purchase decisions was unknown — and potentially large.
Research diagnosis
After the post-COVID correction, the site was underselling the strongest reason to buy.
Customers were not primarily asking for a broader sustainability story. They needed immediate confidence that the wool shoes were comfortable, premium, durable, and low-risk to try.

04The Approach
The work became a research-backed testing system.
We began with a Category Entry Point (CEP) analysis — a deep research methodology that maps the specific situations, needs, and motivations that bring customers to the brand. This revealed a critical insight: 'Initial Quality Perception' was the number one purchase driver for Giesswein customers.
Customers weren't primarily buying for sustainability or eco-consciousness (which Giesswein had been emphasizing). They were buying because they perceived Giesswein shoes as premium quality. The Merino wool wasn't an eco-story — it was a quality-and-comfort story.
Armed with this insight, we designed a testing program that doubled down on showcasing quality throughout the customer journey. Every test hypothesis tied back to the core driver: making the quality of Giesswein products immediately visible and tangible in the digital experience.
Scientific operating system
The roadmap turned quality perception into visible PDP, PLP, and cart proof.
Instead of broad redesign work, the tests focused on precise confidence builders: Merino material cues, guarantee modules, comparison visuals, product videos, and checkout reassurance.

How Giesswein turned quality perception into a three-year testing system
The program followed the DRIP thesis: predictive consumer research identified the real purchase driver, rapid A/B testing made that driver visible across PDP, PLP, and cart surfaces, and iterative prioritization kept the roadmap tied to revenue exposure.

06Key Tests & Results
What the actual tests looked like.
The page keeps the real control, variant, and result screenshots so the case study shows the evidence behind each claim.
Value Perception Badge on PDP
Added a prominent '100% Merino Wolle' badge directly on product detail pages. Rather than burying the material information in product descriptions, we made it immediately visible as a quality indicator — not an eco indicator. The badge leveraged the 'Initial Quality Perception' driver identified in the CEP analysis.

Material & Maintenance Highlight
Created a dedicated section on product pages highlighting material properties and care instructions. This positioned Giesswein's wool as a premium, long-lasting material — reinforcing quality perception and addressing durability concerns that prevent purchase.

Quick Add-to-Cart on PLP
Added an 'In den Warenkorb' (Add to Cart) button directly beneath each product tile on the product listing page, enabling one-click add without visiting the product detail page. This leveraged cognitive ease, decision simplification, and action bias — reducing friction between browsing and buying by eliminating an entire page load from the purchase path.

Overall Impact
The output was not a nicer website. It was a better revenue system.
Over three years, the optimization program generated €12.2M in additional revenue for Giesswein — a 25.3x ROI on the engagement.
The biggest single impact came from the Value Perception badge test, which alone added €232,500 per month in additional revenue. This single test demonstrates how finding the right psychological driver and amplifying it can have outsized impact.
Beyond the revenue numbers, the CEP analysis fundamentally shifted Giesswein's understanding of their own brand positioning. The insight that quality perception — not sustainability — was the primary purchase driver informed not just CRO but broader marketing and positioning decisions.
The Takeaway
The advantage came from compounding learning.
The Giesswein case illustrates a common and costly mistake: brands often optimize for what they think customers care about, not what actually drives purchase decisions. Giesswein was emphasizing sustainability when customers were buying for quality. That misalignment meant the site was underselling its strongest value proposition.
The €232,500/month badge test is a perfect example of how small, specific changes grounded in real psychological research can have enormous impact. It wasn't a redesign. It wasn't a new feature. It was a badge — positioned correctly because the research told us exactly what mattered.
For premium brands experiencing post-COVID corrections: the fix often isn't to discount or diversify. It's to understand — with data — what your customers actually value, and make that value impossible to miss.
Commercial proof
The biggest wins came from making premium value impossible to miss.
A single badge generated €232,500 per month, and the full quality-led system produced €12.2M across three years.
