Hello! We moved into an 80ish year old house and underneath the wall to wall we discovered beautiful hardwood floors. We had them sanded, sealed and coated with polyurethane by a very reputable company. He advised us not to walk around in our barefeet but my husband says that is only if our feet are wet. I think my husband may be wrong but I would like to know why barefeet are not a good idea. We love the floors. Thay are old growth oak with dark mahogany perimeters and scroll work in the corners. Thank you for taking the time to answer.
