The Silent Pollution of Worn-Out Shoes: Understanding the problem to better address it with our Goodyear welted Boots.

Every year, more than 20 billion pairs of shoes are produced worldwide. Most of them are glued models, made quickly, sold at low prices… and thrown away just as fast. The result: shoes have become one of the most problematic wastes in the textile industry.

The Damage of Fast Footwear

People often talk about fast fashion, but rarely about fast footwear. Yet, shoes are one of the most polluting segments of the textile industry. Their environmental impact isn’t immediately visible: a worn pair doesn’t take up much space in a trash can. But when multiplied by billions of units produced each year, it becomes a massive, complex problem that is still largely ignored by the general public.

The main reason is simple: most shoes sold today are glued products, designed to be manufactured quickly, sold quickly, and replaced quickly. This industrial model has a direct consequence: the average lifespan of a glued shoe rarely exceeds one year. Moisture, temperature fluctuations, and repeated mechanical stress quickly degrade the adhesives, causing the sole to come off — the main reason for disposal. Consumers often buy a new glued pair every 6 to 12 months, production starts again, and the cycle continues. Behind an attractive price lies a significant environmental cost, driven by the increase in raw materials, transportation, and waste.

The internal structure of glued shoes relies on a layering of synthetic materials — EVA or PU foams, synthetic textiles, composite rubbers, hot-melt or polyurethane adhesives, internal plastic reinforcements — assembled with hot-melt glues that cannot be separated.
This material complexity is the main obstacle to recycling. Mechanical recycling processes (shredding, density separation) are ineffective, and chemical processes (solvents, pyrolysis) are too expensive or energy-intensive to be industrialized on a large scale.

These shoes cannot be resoled. They therefore end up being incinerated (emissions of CO₂, NOx, volatile organic compounds) or in landfill, where the polymers take decades to break down.

The Goodyear Welt Solution

In the face of this disposable mentality, there is, however, a proven alternative: the Goodyear welt. This traditional construction, which originated in the 19th century, is based on a simple yet revolutionary idea in today's context: a shoe should be assembled mechanically, not chemically.

The welt is stitched to the upper, the insole is made of firm leather, the cork filler gradually adapts to the shape of the foot, and the outsole—whether leather, natural rubber, or technical rubber (such as Dainite or Vibram)—can be replaced without affecting the upper structure.

Nothing is glued permanently. Everything is designed to last, to be maintained, and to be repaired.

This architecture changes everything. A Goodyear-stitched pair can accompany its owner for ten, fifteen, sometimes twenty years. Not because it is indestructible, but because it is repairable. Resoling gives a second life to the shoe without wasting the upper, which represents the majority of the material and work.

Where a glued shoe becomes waste as soon as the sole comes off, a Goodyear shoe enters a virtuous cycle: use, maintenance, repair, extension. The environmental impact is then profoundly different. Over a ten-year period, a consumer of glued shoes will have thrown away five to ten pairs. A user of Goodyear shoes will have kept the same pair, only replacing the sole when necessary.

In term of budget, on one side the customer spends around 100€ each year to renew glued shoes, or 300-400€ on a 10 year period for a solid goodyear-welted pair of shoes (eventually with some affordable refurbishments).

The volume of waste drops drastically, as does the consumption of raw materials. The materials themselves — full-grain leather, cork, natural rubber — are nobler, more durable, and easier to valorize at the end of their life than synthetic composites.

It’s not just a question of ecology, but also of engineering. The Goodyear is a technical response to a technical problem: how to design a product whose life cycle doesn’t end at the first sign of wear. Where the low-end industry has chosen speed and minimal cost, the Goodyear chooses dimensional stability, mechanical strength, and reparability. It’s a design philosophy that rejects planned obsolescence and gives meaning back to the object.

At Lion Boots, this approach is not a marketing pitch: it’s a structural commitment. Offering Goodyear-welted boots means rejecting the throwaway logic and supporting a more responsible vision of footwear. A vision where you buy less, but better. Where you take care of what you own. Where you believe that a well-designed product should last, be repairable, and be passed on.

In a world saturated with disposable products, choosing a durable pair is a tangible, measurable, and deeply modern act. It means reducing your impact without giving up style. It means prioritizing quality over quantity. And finally, it means taking part in a necessary transition: toward a more conscious, respectful consumption that aligns with the environmental challenges of our time.
