Aerodynamics. Or something.

One of the quirks of these kittens is their furry back feet.  Whiskers' are wild, the fur growing in all directions, like an ewok or something.  Snowy's feet have pointed tufts of fur that remind me of the fins on a classic car.  They both are very good at sliding on the wood floors, perhaps due to this special feature.  Who knows?  Regardless, it is charming.  At least to us. :)
