Changing shoes can be practical at home but difficult in hotels, offices and shared spaces. Passive systems capture soil and moisture; direct sole treatment is a separate approach that requires specific efficacy testing.
Stops the same sole continuing through indoor spaces.
Intercepts some dirt, particulates and moisture.
Removes material present on the sole surface.
Needs validated performance for the claimed objective.
1. Removing shoes: a behavioural barrier
Removing shoes prevents the same sole from continuing through the indoor space. It is easy to apply in many homes, but depends on user compliance, a practical changing area and cultural context. The sources reviewed here do not support assigning a quantified health benefit to this practice in every setting.
2. Passive entry systems: capturing tracked-in material
EPA and LEED treat mats, grilles and walk-off systems as tools for intercepting soil, particulates and moisture. Their function is mechanical and depends on dimensions, materials, maintenance and the path users actually take. They are not, by themselves, shoe-sole disinfection systems.
3. Cleaning or treating the sole directly
Acting on the sole surface is a different category from passive capture. The 2016 systematic review assessed several decontamination approaches without identifying one that was universally and consistently effective. Any new technology therefore needs testing that matches the method, target and intended use environment.
The right comparison depends on context
A home may combine a shoes-off routine with cleaning when needed. A high-flow building may favour solutions that do not require major behavioural change. In either case, the decision should begin with the problem being managed — visible soil, moisture, particulates or a defined treatment objective — rather than a generic promise of “hygiene”.
Where HOME KLINX fits
HOME KLINX explores threshold treatment as a complement to existing practices. It is not presented as an automatic replacement for floor cleaning, shoes-off policies or passive systems. Its value must be demonstrated through measurable performance on the real system.
A behaviour-first conclusion
The best threshold strategy is the one occupants can repeat consistently. Shoes-off behaviour may be excellent in one household, while another may need a combination of walk-off surfaces, staging and targeted sole cleaning. Evaluation should therefore consider measurable transfer and workable routines in the intended setting.
