Question: When I push the button, how do I know the size?
Document: I bought these for my 8 year old daughter. She had tried several different types of skates and they were always uncomfortable or not warm enough. She tried these on and instantly loved them. She is a recreational skater so because they change sizes, they should last her about 5 years. They adjust very easily with the push of a button and offer great ankle support. They were delivered 4 days ahead of the estimate. We are very satisfied.
It looks good and works fine. My 6 year old loves it. I like that we can change the shoe size.
Beats the heck out of me how to adjust them too. I just depressed the button on one of the skates, and it seems to be stuck in that position, with nothing happening. I bought these because the cheap skate rentals aren't padding and are hurting my daughter's feet. The padding seems acceptable and my daughter was pleased with their comfort. These will have to go back--what a hassle. With just a little better quality, these would have been awesome.
Second issue, is these have a pick on the toe. So if you are NOT used to a pick...  (like my poor kid)..  you will catch and trip on it (especially on the lowest size).She's doing OK now, but I wouldn't even dream of putting these on my kid unless they were fully protected against head injury.On the other hand.. no complaints of cold feet anymore.
I bought these for my 6 yr old girl, who was doing excellent in skating. The draw was the adjustable size. This is actually one of the issues with the skate. When it is at the smallest size, the blades stick WAY out, where normal skates are more proportional. My poor kid (who never fell before), was banged up pretty bad the first session with these. Took her 4 or 5 tries out, before she stopped smashing into the ice.
Purchased three pairs of these adjustable Lake Placid skates for my grandchildren. Good skates except for top straps not staying in place. I have seen all of other negative reviews and totally agree that the problem should have been fixed before they sold any more of these. I have had three grown children who played hockey for years, so I have some experience in grading skates and these because of the top strap are not safe. Anybody know how you contact Lake Placid?
Very good quality, no problems with the plastic strap. Fit my 4 y.o. daughter perfectly, her regular shoe size is 11.
Lots of ankle support for my 5 yr old. She'll be 7 this year and still wearing them! Easy to change the size and very sturdy for beginners.
I love that my daughter can grow into these! Now for the weather to warm up a little so we can go try them out! She is very excited about them!
My daughter was pleased with the skates for my grandkids. I will plan on using this site again for further purchased if needed by my family.
