Do these mats leave marks on your hands/shoes? We want this for our home gym/kid's play area but are concerned the kid's hands/feet will turn black from the flooring.
Our 8mm Strong Rubber Rolls are not painted, so there shouldn't be any transfer of black coloring on any articles of clothing or body parts. We do recommend cleaning the flooring once it is installed, as there will be some dirt and grime from the manufacturing, shipping, and installation processes.
