Old man story. I purchased one full size mat last year. It was a bit wider than my parked Honda Ridgeline. The rest of the concrete garage floor was bare and smooth. Was going to buy a second mat which would cover the rest of the floor. I thought. They are not cheap. A few weeks later went outside the garage barefoot and walked on the wet driveway. Upon entering the garage with two wet feet and smooth concrete. This resulted in an immediate physics experiment. Result: Fat old man with wet feet walking on smooth concrete noticed both feet were eye level. Rapid decent and boom. Split the legs like a gymnast without grace and control. Banged up a bunch of body parts. Practiced colorful language and vowed to buy the second floor cover. Oops forgot. 60 days later a repeat experience. Still hurt. Shame on me. The second cover was the charm. My only complaint with the material it is crud friendly. It easily collects loose grass, pup hair, sand and dead bugs. Good luck with your wet feet on the smooth concrete. The mat is Strongly recommend.
