Concerned about the odor as these are made from rubber, is there any?

Our 15mm Impact Tiles - Designer Series will have a slight odor to them. If you are sensitive to the odor, we recommend mopping the floor with a mild soap and water solution and then letting the flooring air dry. You may have to repeat this process a few times to really dissipate the smell. The smell is not toxic, so don't fret; It's just a foreign smell similar to that of new clothes or shoes.
