Whether it's sneakers, athletic shoes, slippers, soccer cleats, or even your favorite Birkenstocks: smelly shoes are a common problem. From sweat odor to damp smells and even the scent of cat urine, we've all experienced it. In this blog, we'll explain where it comes from and what you can do about it.
Why do shoes smell, anyway?
Shoes smell mainly because they are a breeding ground for bacteria. These bacteria feed on sweat, moisture, and dead skin cells, producing unpleasant odors. Athletic shoes, for example, often smell of sweat due to intensive use. But also wet shoes that can't dry properly, such as after rain, quickly start to smell musty. Even leather shoes, slippers, or orthotics can retain odors.
And sometimes shoes smell so intensely that people say, "My shoes smell like cat urine" or "My Birkenstocks smell like sweat." Especially in warm or humid conditions, bacteria thrive.
Which shoes smell the most?
- Sneakers & athletic shoes: often due to sweat and daily use
- Soccer cleats: often wet and worn on grass or artificial turf
- Slippers & house shoes: we wear them a lot, but rarely wash them
- Orthotics & sandals: absorb a lot of sweat and dry poorly
- Leather shoes: can retain moisture without you noticing
Brands like Adidas sandals or Birkenstock sandals are also known to retain unpleasant odors over time.
What can you do if your shoes smell?
Common household remedies like baking soda, vinegar, or deodorizing sachets help temporarily but do not solve the problem structurally. It's important not only to mask the smell but also to tackle the cause.
