The foam really helps in not hurting your feet after using it for a while.

Usually I had to stop playing once my feet started to hurt, but now I stop when I just can't move my legs anymore

The plastic can burn your feet if you move too fast

My feet got blisters however, so I wouldn't recommend playing for too long at first

Metal mats hurt the feet while the foamy ones don't and cushion the fall of your feet.

Play ONLY WITH SOCKS, bare feet can stick to the surface of the mat and after prolonged use you can eventually rip it
