Question: Size chart for Chicago roller skates?
Document: My son had the smaller size of the Chicago Boys Sidewalk Skates and asked to get the same in a larger size. They are well worth the price and held up well.
I have 2 pair of these Chicago Boys Sidewalk Skates for my kids. They love these skates! They are very well-made and worth the money! My kids are hard on these skates but they have held up very well for 5 months of weekly use! The wheels are all messed up now, of course, due to the cement & asphalt but that's normal when you let them skate outside with them instead of only at a roller rink. They are still skating fine on them, however. I may replace the wheels in a couple more months.
got this Roller Skates for my 6 year old son,he is a beginner and loves this Skates.the shoes are very comfortable,no signs of any pain after taking it off.If you planning on buying the skates by a shoe size bigger.Overall very pleased with the Item.
My 6 year old son got them this summer, he's been happy and I think they are very good. The only thing I would recomend is to order one size up, I did because somehow I stumbled upon this site with a chart that gave instructions on how to order for different brands depending on your street shoe size, I was hesitant buy I'm glad that I ordered one size up.
I brought these skates for my 9 yr old. The worst skates ever. The wheels are very rough and it's not durable for the outdoors. The Chicago bullet skates are 10 times better. Don't waste your time buying these.
These boys' roller skates are great quality for kids who are beginners to intermediate skaters. My 5 year old nephew loves them and I was so inspired that I ordered some skates so I could go skating with him!
My son has never tried roller skating or roller blading before, and was quite excited to try it out.These skates are more for indoors than outdoors. It was advertised as both, but technically, they don't work as well for outdoor use. If your kids are active like mine, make sure that the wheels on the skates are rubber for outdoors if you want to prevent a lot of falling and stress during the learning process.
I chose the Chicago brand from past experience, and I was not disappointed. We are a three generation family of Chicago skate users, and the quality of workmanship is still there after all these years. Upon examination of these skates, I found them to be sturdy and well balanced, with excellent stops, and "stylish" enough to please the 9-year-old they were purchased for. I would recommend these skates to anyone who wants the child in their lives to have the safest and best skates money can buy; price-wise, you can't go wrong with these.
My 9 year old grandson loves these. Easy for him to get used to and learn to skate .Great buy and Amazon's  service is fantastic.Chicago Boy's Sidewalk Skate
