Soft-Spike Massage Balls, Red, 9cm

Can't do without these!I even carry them on airplanes to place in my lower back for support on those horribly designed seats. After a long flight, there's nothing like rolling one between my shoulders/back and a nearby wall to release the tension.They're great when lying down to release tension in the back, shoulders - even the behind, which helps release tension in the hamstrings too.I don't understand why the description says to use them on your feet. There are much better items out there for that. I'd imagine these are dangerous to use while standing since they can roll out from under you.If you're looking for something for feet, try "soft spike balance pod" or just go to a toy store and get some of those small, hard balls that bounce really high (super balls) - about 3/4 -1 inch diameter - and press or roll one under one foot while you stand holding onto something for balance. Start with a little weight on it, then increase as you go. Best massage ever. Learned it from my Pilates instructor.

The ball is fine and exactly what I expected. The advertisement was misleading. I thought I was purchasing a 3 pack of balls of different sizes. When I only received one for the price, I was very disappointed.

The ball is large enough to give an effective massage in areas such as the small of the back. It is firm enough to give an effective massage, but it is flexible. You don't have to wait to get a massage. You can place the ball behind you against a wall and roll it with as much or as little pressure as you need.

This ball is smaller than I expected and doesn't stimulate my foot like I had hoped. Unless I am standing, I can't get enough stimulation to do the job.

These are the best massage exercise balls I have ever used, they are easy to use and can be taken any were and used everywhere. The massage balls work well for me, I use them for my painful knees and back. I get relief from the use of the balls and am able to get a better night sleep.

This ball has the perfect density for full body rolling and it works equally well for rolling out your feet. The nubbies are not too sharp or too wimpy, just the right fit for this Pilates Princess. The 9cm size ball works well for those tight spots you just can't reach any other way.

The product is too hard and doesn't have much "give". The little nubs hurt. I had hoped it would be softer.

Pretty useless...
