How have we not spotted this before? On Sept. 24, a particularly observant KUWTK fan eagle-eyed a gross Kardashian family habit and now, we can think of anything else. “Does anyone else [notice] how they all put their feet on the couch… with their shoes on[?] I just don’t get it,” the user wrote. 

Not only did their tweet garner the attention of the entire internet, but Kim Kardashian herself replied! “OMG we do! It is pretty gross,” the 37-year-old agreed. For those of you who need a little convincing, look no further than the image below. P.S. It was taken from the most recent episode of KUWTK, so you know this isn’t old news.

OK, now that we’ve sufficiently provided evidence, let’s move onto the fan reactions. As it turns out, there were a few people who actually tried to offer some insight into this unhygienic behavior. “It’s probably the first and last time they’re wearing the shoes anyway. I bet they’re even cleaner than the couch” one user offered. “I honestly just assumed they were ‘indoor sneakers,'” added another. 

Some international viewers of the show, however, reasoned that it must be a cultural thing. “Honestly, I thought this was an American thing. In Norway, we don’t wear shoes inside at all… ’cause, you know, that’s really gross.” Another added: “I don’t understand why Americans never take off their outdoor shoes when they enter a house.”

To clarify, there’s nothing inherently American about putting your shoes on a sofa. If anything, this particular habit is solely reserved for the Kardashian family (or maybe abundantly wealthy people in general, who knows?).

It’s a head-scratcher, for sure, but you don’t get to be the most famous family in the world without a few quirks, right? Be warned: Don’t you dare go putting your feet on the furniture at your grandmother’s house just because the Kardashians do it — you will live to regret it.
