Alot of people still don't remember how important it is to prevent sand and other build up to occur on your wooden type floors. (this would include hardwood flooring, cork flooring, bamboo flooring and really any hard surface flooring.)
It's not that people think that sand or dirt is good for floors, but we sometimes get a false sense of security about the scratch-ability of flooring due to the big warranty labels that now show on most flooring brands.
BUT ALL FLOORING, no matter how tough it is can be scratched. Sand can act as sandpaper under your feet therefore keeping the floors sand and dust free is critical. One of the best ways to reduce the sand and build up on your floor is to have mats both inside and outside your doorways (yes, all of them). These mats will protect your flooring by helping grab most of that sand off the shoes before they hit your floors. You also want to have a very regular dust mop schedule (or vacuuming) to keep those floors in tip top shape.
No matter what warranties claim, no matter what sales people promise, no matter what anyone says - FLOORING can scratch. There is no warranty against scratching. (Although there are some very resistant floors to scratching, let's all just remember that the laws of physics still apply to flooring.)
This is somewhat redundant to some past posts, but I wanted to just share this important point since this topic can never get old.
