I'm not brave enough to put a nice wool rug in the kitchen. So while I love the look, it's not happening-- considering the egg and bowl of chocolate sauce I dropped last week, that's a good thing! Instead, I use outdoor rugs. They're made to withstand a lot, so they hold up great in kitchens (ditto entries/mudrooms).
I've had the first rug in my kitchen for two years. It's made of recycled plastic bottles and it's basically indestructible. Admittedly, outdoor rugs aren't the nicest thing underfoot. But to me, the easy cleanup is worth it.
