Query: FOAM GRIPS???

FOAM grips??? How about hard rubber. These don't have FOAM grips by any stretch of the imagination. The wheel tread is the same very hard rubber. They should've gone the extra mile and put real foam grips on; I would've been happy to pay the extra money to have it be foam like the ab wheel at my gym. I was really disappointed. I think this is false advertising. It does do what it's supposed to do, I just think they should've said 'hard rubber grips'.
