We asked some of the country’s leading germ scientists whether changing into Kyrgies at the door made a difference.

Their peer-reviewed study is finalized. We’re waiting with baited breath for it to publish. In the meantime, we can give you some high-level takeaways:

According to published, peer-reviewed research by scientists at the University of Arizona, the average synthetic rubber outdoor shoe sole harbors hundreds of thousands of bacteria. A new study by the same lab — still independent, but this time paid for by Kyrgies — confirmed this reality. Scientists found coliforms turned up on about 96% of shoes their lab tested. Plenty of E.coli was prevalent too. Ew. What lands on the sidewalk comes home on our shoes.

In the new study, subjects wore shoes in the house, and the scientists swabbed the floor for bacteria. And in a separate trial, test subjects took off outdoor shoes at the door and changed into natural-soled Kyrgies. We'll wait for publication to share all the findings, but here's a teaser: When scientists swabbed the floor again, ran the numbers, compared the datasets, they saw evidence that taking off shoes at the door and changing into indoor-only shoes with natural-material soles were associated with less bacteria on the floors — a reduction of more than 72%.

Materials matter

Why? Smooth synthetic or rubber soles transport germs and spread them around. Taking shoes off at the door reduced the bacterial load, while at the same time, past studies have also shown that natural materials like vegetable-tanned leather are active surfaces. Leather’s fibers and tannins may slow bacterial growth, and the porous structure can trap bacteria where it dies off, reducing the spread.
