Question: what size is it
Document: My son is 3 years old and he`s 9 size shoes, but i don`t know if he fits on those spiderman roller skates...? can you help me? ?
My gs loved these and since they have adjustable wheels he is skating at 2. Perfect for toddler and grows with them in size. Fits sizes 6 to 9
Great for beginner and easy adjustable size but wish the tires were better. Rubber is best for beginners and these tires are mainly all plastic. Also the buckles kept unbuckling when he fell and that got annoying. He loves them though
Perfect for my 3 yr old! He had been asking for skates after we have been on so many bike/rollerblading trails this past summer! Hes still trying to get the concept but we can adjust size and switch from skates to blades whenever he's ready!
I love that these work like with training wheels and also can be used as normal roller blades once the second wheel in back is not needed. My son is two wears size 7 shoe and these fit and I can make larger. he is in the smallest they go and he is really skinny.
The skates are cute. My son is 6 and wears a size 12 shoe. These fit him, but probably won't if he grows much more. They do adjust, but his foot is just about the limit of that. The only issue is the clip on the one skate will not stay shut. I have to play with it and mess with it before it will finally snap in place. And one bump or fall and it pops up again.
This is a very practical roller skate for very young kids just learning skating. It has two wheels in the rear that can be easily removed and configured as in line skate with one wheel in the front and one in the rear. The size is adjustable as well which means more life time and I don't have to replace it soon. I very much would recommend it to junior kids who are new to skating.
We opened the box and switched the wheels side by side before giving them as a present. Had to rethread the bolt to make it work, not real impressed. My son has size 7 feet now, I wonder if he will still have small enough feet by the time hes ready to take them out without our help. The other reveiws talk about the latches not staying in place... but we have had no problems with that or anything other than the bolt.
I love the idea of skates that convert to inline. So cute and my 4-yr-old loves them, but they are extended to maximum length and he can bary squeeze his foot in. I am hoping they will even last the whole summer. Better for kids with very small feet. He is just not ready for real roller blades yet. Hoping there is something like this that may go to a bigger size. Other than being small, great product!
These skates are very cute, but the size really only works for up to a size 10 Max.We ended up purchasing the chicago boys skates instead and gave these to his 3 year old cousin. The quality is not as good as the roller derby brand ( which we bought for his sister ). The 3 year old was able to navigate the rink without assistance using these. He still fell, but the inline with two back wheels was easier for both boys than traditional roller skates at the rink.
