In the hospitality industry, guest safety is non-negotiable. From hotel bathrooms to spa environments and poolside areas, slippery surfaces present a real and often underestimated risk. Yet, many disposable or amenity slippers still fall short when it comes to reliable grip.
At Primal, we set out to change that.
Why Anti-Slip Slippers Matter in Hospitality
Slip and fall incidents are among the most common causes of guest injuries in hotels. Wet tiles, polished stone, and smooth surfaces significantly increase this risk, especially when paired with low-quality slippers that lack proper traction.
For hotel operators, this is not just a safety concern but also a liability issue. For guests, it directly impacts comfort, trust, and overall experience.
This is why anti-slip performance should be a core design requirement, not an afterthought.
Moving Beyond Basic Grip
Most slippers on the market rely on minimal texturing or low-cost materials that provide inconsistent grip, particularly in wet conditions. True anti-slip performance requires a more advanced approach that considers:
-
Material composition
-
Surface contact geometry
-
Outsole pattern design
-
Pressure distribution underfoot
At Primal, we approached slipper design as a technical challenge rather than a commodity product.
Achieving EN ISO 13287:2019 Certification
Our latest generation of biobased and biodegradable flip flops has been tested according to EN ISO 13287:2019, the leading standard for slip resistance in footwear.
The results:
-
Certified performance on dry tile
-
Certified performance on wet tile
This standard evaluates the coefficient of friction under controlled conditions, ensuring that the product delivers reliable grip where it matters most.
For hospitality partners, this provides a clear and credible benchmark for safety performance.
Design Principles Behind Anti-Slip Performance
Achieving this level of performance required a combination of design and material innovation:
1. Engineered Outsole Geometry
We developed a refined outsole pattern that maximizes surface contact while allowing water displacement. The groove depth and spacing are carefully calibrated to maintain grip without trapping moisture.
2. Material Selection
Our biobased materials are optimized not only for sustainability but also for friction performance. The compound balances softness for grip with durability for repeated use.
3. Pressure Distribution
The sole design ensures even pressure across the foot, increasing effective contact area and reducing localized slipping.
4. Consistency Across Conditions
Unlike many alternatives, performance is maintained across both dry and wet surfaces, which is critical in real hospitality environments.
Sustainability Meets Performance
Traditionally, there has been a trade-off between sustainability and performance. Many eco-friendly slippers compromise on durability or safety.
At Primal, we believe this trade-off is no longer acceptable.
Our flip flops are:
-
Biobased
-
Biodegradable
-
Designed for circularity
-
Engineered for high performance
This means hospitality brands no longer have to choose between environmental responsibility and guest safety.
What This Means for Hospitality Brands
By integrating high-performance anti-slip slippers into their amenities offering, hotels and resorts can:
-
Enhance guest safety and comfort
-
Reduce risk of slip-related incidents
-
Strengthen their sustainability positioning
-
Differentiate through thoughtful product design
In a market where details matter, even a slipper can become a statement of quality and care.
The Future of Hospitality Footwear
Anti-slip performance will increasingly become a baseline expectation rather than a premium feature. As standards evolve and guest awareness grows, hospitality providers will need to rethink even the smallest elements of their offering.
At Primal, we are proud to be at the forefront of this shift, combining certified safety, sustainable materials, and design innovation into a single product.
