Santa placed this great gift under the tree for my very active 7 1/2 y/o son. He received the black model, which appears to be identical to the purple other than the color of the platform. He's been practically bouncing off the walls ever since he opened them. In reality he gets between 6 inches to about 2 feet off the ground depending on how hard he jumps.

The base is very heavy duty, and looks very similar to an automatic lawn sprinkler valve box. There is a foot platform suspended in the middle of the base by way of heavy rubber or polyurethane bands. The bands run through slots in the platform and attach at either side of the base by hooking over some plastic teeth surrounding the outside of the base. There are 12 points of attachment for each foot platform.

Some assembly is required, the most difficult thing is stretching the bands. Santa's elves pre-assembled my son's so they'd be ready to go as soon as he got them. I think he could have put it together himself in about 5 minutes.

The set comes with a 1lb bag of bands that are used in increments up to 5 per platform slot to accommodate the 60 - 160 + lb weight rating of the user. The 1lb bag of bands had 50 total bands. The weight chart on the instruction sheet lists up to 5 per slot, which would equate to 60 bands, so I'm guessing there must be replacement/upgrade bands available.

1 band per slot = 60 lbs or less
2 bands per slot = 60 - 100 lbs
3 bands per slot = 100 - 130 lbs
4 bands per slot = 130 - 160 lbs
5 bands per slot = 160 + lbs

I think the real limit with the design is the size of the user's foot. I have a size 14, and weigh 200lbs so I can't try it out. :-( It looks like a lot of fun, and my son has been having a blast with it.

It's a pretty simple toy, but my son loves it. Sometimes simple things are better. In fact he's been using it more than the Playstation 2 games he wished so much for. 5 stars

My kids wanted moon shoes for Christmas but because of the varied reviews on Amazon I was leery of buying them. So I contacted our local TV station that does a "Try It Before You Buy It" segment on their Wednesday evening broadcasts. Well they wanted to have my kids try them so they bought two pair of moon shoes and brought them to my house on Friday. The kids were ecstatic! We put to the task of putting the shoes together. That was a little confusing. The cameraman had to help us! There are large black rubber bands that have to be attached to the bottom of the shoes. The weight of your child will determine whether you attach 1 to 5 bands in each section of the shoes. Once we put them together the kids had a ball. I was a little leery at first but they haven't taken them off their feet since they got them. I would say that they are a success! 4 stars

Some reviewers here give these shoes a bad rap. OF COURSE you should wear a helmet and wrist guards with these shoes, just as you would with a skateboard. Then you won't be in danger of 'busting your head open,' like some reviewers warned. My 5 y.o. daughter and 8 y.o. son LOVE these shoes. They jumped and ran in them for hours - usually under my supervision. Two recommendations - 1) put on more rubber bands than recommended for your child's weight so they aren't so 'squishy', and 2) buy extra because they break kind of frequently. But well worth the active fun! 4 stars

Don't let the picture fool you, these shoes DO NOT make you jump as high as the moon. In fact, even the most highly-trained athlete wearing these shoes would only be able to jump as high as the clouds.

While gravity and shoddy craftsmanship might limit your jumping potential, your imagination will allow you to leap to the stars! That's the best part about Black Moon Shoes -- it's not about how high you can or can't jump -- it's about how high you WANT to jump.

So when it comes to using your imagination and developing important motor skills, Hart Enterprises' Black Moon Shoes are leaps and bounds above the competition. 1 star

These shoes are great.The other kids that wrote a review are not using these shoes right. You where socks and tennis shoes with moon shoes.If you use them right they will make you feel like your on the moon.I once bounced THREE FEET OFF THE Ground!You can use these inside and outside.there very stable. Thatis why it makes sense to call these shoes AWSOME!
