Question: how hard is it to find replacement parts (wheels) and have you used these on the street?
Document: I ordered these skates for my son's 10th birthday present. They came well packaged and when he opened them he loved them. He has been using them everyday since his birthday. He truly enjoys them and they are very well made and durable. My 10 year old is very active and uses the skates in our drive way and up and down our street. I would recommend this product to anyone looking to buy skates for a youth.
My 5-year old is really loving these. I can't imagine a better pair of inline skates for the money. One of the things I was most impressed with was how well the wheels roll. If you physically spin each wheel they don't stop for several seconds. One of the most fundamental skills of good skating is to be able to skate on one foot. This allows time for a good push with the other foot as well as the ability to do good crossovers.
Work great!
We were renting skates every time we went to the rink and my son asked if we would buy him a pair. I was hesitant, since he grows faster than a weed! But these will grow with him and he loves the fit!
Very adjustable and easy to adjust too! I bought them for my son but my daughter can wear them too, and they even fit mom and dad!
The skates are just what our 8 year old grandson wanted! He is able to put them on and go. The quality is excellent. These skates will last him for a couple of years at least. He wears a size 4 shoe. The fact that these adjust from size 5-8 and the Rollerblade brand made these the perfect choice! He says they are very comfortable.
That's not a problem with these. My boy has improved exponentially after getting them (he learned on crappy rental skates at the local rink). Great for outdoors AND indoors. Highly reccomend!
Not good. Two different skates. Have to return from overseas.
My 12 year old loves them and they are very well made. We are glad wee decided to spend the extra money for these. Changing the size couldn't be easier.
He's an expert now. I think that the fact that they can grow with him is great. Delivery was quick and the rollerblades were as described.
Answer: yes
