Wet footwear isn’t just uncomfortable - it’s a breeding ground for bacteria, odour, and damaged shoes. The Atacama aims to solve this problem efficiently, but what’s actually happening under the hood? The answer lies in a smart application of thermodynamics, fluid dynamics, and material science.
In July 2024 I travelled to China to meet manufacturers of heating and drying products. It was a fascinating trip on a number of levels and I very quickly found our perfect manufacturer. Almost two years later, we have a fantastic relationship and we’ve had no complaints about the design and effectiveness of our dryer.
A bit more of a deep dive below on our design.
1. Controlled Heat Transfer: Speed Without Damage
At the core of the Atacama dryer is heat - but not too much. The Atacama system uses low-temperature convective heating, typically in the range of 35–45°C. This is warm enough to accelerate evaporation but below the threshold that could warp adhesives, shrink fabrics, or crack leather.
The principle at work is simple: increasing temperature raises the vapor pressure of water, allowing moisture trapped in shoe materials to transition into vapor more quickly. The challenge is maintaining a safe, uniform temperature across different materials, which is where design matters.
2. Forced Convection: Moving Moisture Out
Heat alone isn’t enough. Without airflow, humid air lingers and slows down drying. The Atacama dryer uses forced convection - a fan-driven airflow system - to continuously move warm air through the interior of the shoe.
This does two things:
Think of it like wind on a wet day. It dries clothes faster not because it’s hotter, but because it keeps carrying moisture away.
3. Airflow Engineering: Reaching the Hard-to-Dry Zones
Shoes are complex structures with tight spaces - especially in the toe box and inner lining. Effective dryers use directional vents or nozzle systems to push air deep into these regions.
The Atacama design typically emphasises:
This is a subtle but important application of fluid dynamics - ensuring airflow isn’t just present, but purposeful.
4. Moisture Management and Odour Control
Drying isn’t just about water - it’s also about what comes with it. Sweat introduces organic compounds that bacteria feed on, leading to odour.
By rapidly reducing moisture levels, the dryer disrupts the environment bacteria need to thrive.
Even without those, simply drying faster is one of the most effective odour-prevention strategies. Check out the unique Ozone feature which circulates warm and cool air on rotation.
5. Energy Efficiency: Small System, Big Impact
Compared to traditional drying methods (like radiators or tumble dryers), a dedicated shoe dryer uses significantly less energy. This efficiency comes from:
It’s a good example of how focused design can outperform general-purpose solutions.
Why It Matters
For athletes, outdoor enthusiasts, and commuters alike, keeping footwear dry extends product lifespan, improves hygiene, and enhances comfort. The Atacama shoe dryer isn’t just a convenience gadget - it’s a compact demonstration of applied physics solving a very practical problem.
