Two white sneakers: what the available data can and can't tell us

The white leather sneaker is a wardrobe staple — one of the few items that works with almost everything and barely goes out of style. Similar product photos, however, do not establish that two shoes were made in the same way.

The comparison below is an illustrative scenario built from typical category inputs. It is not a live comparison of two identified products or retailers. Its purpose is to show how price, a category-level estimate and a separate brand assessment answer different questions.

This isn’t a product review or a recommendation. It’s a demonstration of what becomes visible when you look beyond the product photo.

The comparison

Example Ais a hypothetical mainstream athletic brand’s leather court shoe. Virgin leather upper, synthetic rubber sole, made in Vietnam. Retail price around €100. For illustration, its brand-level input is set to “Not Good Enough” (2/5).

Example Bis a hypothetical shoe from a smaller European brand. Leather upper from a certified tannery, natural rubber sole, made in Portugal. Retail price around €120. For illustration, its brand-level input is set to “Good” (4/5).

All values in this table are illustrative. The footprint figures show an important limitation of Kleerdrobe’s current category and detected-material model: with “leather sneaker” as the supported input, both examples receive the same rough estimate. They are not measurements of a real shoe. The rating row demonstrates a separate brand-level signal rather than rating an unnamed product.

What could drive a real difference

In a real comparison, a modelled footprint gap could be influenced by several factors.

Manufacturing energy.The electricity mix and energy contract used by a facility can affect the footprint of energy-intensive cutting, stitching, lasting and finishing. A country label alone does not establish a factory’s energy source. Kleerdrobe does not currently adjust a shoe estimate for manufacturing geography.

Tanning process.The tanning method, wastewater treatment and energy source can affect leather’s result. A certification can provide useful process information but does not by itself supply a product footprint. Our current model identifies leather only as a broad material signal; it does not infer a tannery process or certification benefit from listing copy.

Sole material. Natural rubber has a lower carbon footprint than synthetic (petroleum-derived) rubber in some lifecycle studies, with results depending on the study boundary and sourcing. The current shoe estimate does not apply a sole-material adjustment.

What the numbers can’t tell you

We want to be transparent about the limits of this comparison.

These are estimates, not measurements. We haven’t tested these specific shoes. The CO₂e and water figures are based on category-level LCA data and a supported broad material signal. They are not adjusted for geography, tannery certification, factory efficiency, transport routing, packaging or the energy contract of a specific facility. Those unknowns could make the real figures higher or lower.

The Good On You rating covers the brand, not the shoe. A “Good” brand can still produce a specific product in a problematic way; a “Not Good Enough” brand might make one particular shoe responsibly. A brand rating provides context on company practices such as labour policies and environmental management, but it is not a product guarantee.

And neither number captures everything. Durability, comfort, fit, and personal style are real factors that this footprint estimate cannot measure. A shoe that fits poorly and sits unworn delivers no useful cost per wear, regardless of how responsibly it was made.

Why we show this

The point of putting two products side by side isn’t to declare a winner. It’s to make differences visible that are normally invisible.

When you browse a retailer’s site, you usually see photos, prices, and marketing copy. You may not see enough product-specific evidence to determine the energy mix, supplier transparency or environmental difference. An estimate can highlight questions worth asking; it cannot turn missing evidence into a fact.

Kleerdrobe exists to surface that layer. Not to judge — you might still buy Example A for excellent reasons (it fits better, you prefer the silhouette, the price matters). The goal is to understand what the available evidence supports and where uncertainty remains.

That’s what an informed wardrobe looks like.
