My 9 year old has been wearing the Kingdom GS for a number of weeks.From a parent perspective, it's a great shoe. Easy to get on and off. This shoe color is black which makes it easy to hide stains, and the material was easy to clean. The sole appears to be thicker than other less expensive models so I expect it to last longer before wearing through on the rubber.From a con, there aren't many. I wish the shoe laces were a bit longer to help make double knots before going to school.My 9 year old reported that it was a soft feel, and there was plenty of room for his toes. He felt like there was a spring to his step, and who doesn't like wearing a shoe that LeBron does as well?

I have to admit I was at first excited to see the Kingdom “gs” shoes but upon first glance at the shoes in person I was not blown away at all. The shoes are very much similar to any other basketball shoe as far as appearance goes. They are light in weight but the colors are boring (black and green) and I’m not sure suede is a good pick of fabric for a kids basketball shoe. Kids can be so rough on shoes, especially when playing a sport it is hard to keep that material clean and looking good with each wear. I do like that these shoes seem to run a little bigger in size than most Nike shoes for kids. You can definitely expect your child to have some growing room in these. I would recommend for them to come in more color options instead of the two.Since the shoe does ... MoreI have to admit I was at first excited to see the Kingdom “gs” shoes but upon first glance at the shoes in person I was not blown away at all.

It would have been nice for the kids version to be more versatile so you can get more wear of the shoes.

I love these shoes for my son. As a 7 year old, he doesn’t change shoes to play basketball and then go to school, and these shoes work in all settings. Super comfortable, subtly stylish, and some of the lightest basketball shoes I’ve seen. The details make the shoes. The gel soul color, LeBron signature, and ripple effect all make the shoe unique. My son even talks about how the laces are better than any of his other shoes. His most comfortable shoes yet, and he’s always saying how they make him run faster and jump higher! Hah (PF flyers got nothing one these)

This is a very well made shoe. It's my son's first pair of LeBron's and he was super excited. He's worn them practically every day since he got them. Basketball shoes normally run small so I went a full size up to be safe and they fit well. I could have went just a half size up and that would suffice also. The materials feel really premium to say it's a little kid's shoe which surprised me. I'm used to that type of material on adult items. The upper is a suede type material and the sole is thick and durable rubber. Looking at the color I assumed the sole would glow in the dark but it doesn't. Not a deal breaker though! There's no signs of wear and tear, not even a loose thread. My kid is very hard on shoes and these passed the test. I would definitely recommend to ... MoreThis is a very well made shoe.

The sole is grippy, the suede material is premium, and they are built tough. He'll probably grow out of them because they are built that well.
The fit of the shoe was great as we order a half size up. My daughter usually wears a 1.5 and the 2 fit like a 1.5. The feel of the shoe felt luxurious and the materials felt soft. My daughter shared that they felt smooth and she really liked that about the shoe.The design was nice and it was nice on the eyes. When we got the shoe, we thought my daughter would be out off by the color and style but she was very intrigued.The fabric as mentioned was something we all really liked. It was comfortable and had the effect of the shirts that transform.The thing we like the most was the comfort and the styling of the shoe. My daughter said she felt very comfortable and they didn’t make her feel tired.

Comfortable shoe, but not as good as the 20s (so far). I hope NIke re-releases the 20s.Cons:- Laces - Nike switched from flat laces on the 20 to chunky round laces on the 21. The chunky round laces do not stay tied. I switched back to a spare pair of laces from some older nikes and it was an upgrade.- Colorways - the options on the colorways are not as good as the 20s.- Breathability - I feel like my feet sweat more in these than the 20s.Pros:- Fit - Out-of-box fit and comfort were better than the 20s; the 20's broke in pretty quick.- Cushioning - these feel softer than the 20s from a cushioning standpoint. Feel better after 90+ mins of play.- Eyelets - I didn't have any issues with the eyelets that some other reviewer mentioned. I felt like the eyelets on ... MoreComfortable shoe, but not as good as the 20s (so far).

The outside of the shoe is mesmerizing- it's so silky and smooth to touch. The design could have been brighter in certain areas- maybe the swoosh could have stood out more with the LeBron Logo too. This type of shoe should stand out visually among others.The cushion inside was comfortable and absorbed shock well. It provides a solid, sharp launch from run to stop. The grip on the outer sole kept down slipping during power moves. My son said he could jump higher and Run faster than normal as a result. Excellent traction control. I loved the fit and mobility of the shoe. Upstanding job on the traction of this shoe. Mid sole provided him great ability to jump higher and run faster. Great shoes for a child playing guard position.
The Kingdom Gs are just as their name states. Crowned to be king of the courts. These sneakers come with a bottom sole that have excellent grip and sleek design equipped with the technology of Air Zoom to give that cloud feeling while balling up. The Cushlon 2.0 creates a lightweight shoes that provides stability and support for on and off the courts. The Kingdom Gs are just as their name states. Crowned to be king of the courts.

My son was a huge fan of the kingdom gs shoes. He typically doesn’t like shoes you have to tie chase he’s still learning but boy did he love these! They are very comfortable and easy to put on and take off. He was excited to tie his shoes and wear them all day. He loved how stylish they are as well. He loved the feel of them as the material is unique and smooth. He felt they made him faster and was able to jump a bit higher. I would highly recommend these shoes for any kids that are super active and complain about comfort, because these shoes are as comfy as they come!
If you are like and and have a girly daughter that also loves sports these are for you. I loved the fact that they are very light weight which makes them great for carrying around to and from school and practices. My daughter especially liked that fact that they had a "vibe" from a certain female pop star. I personally loved the gold detailing at the back of the shoe. Finding sport shoes for a girl can be hard sometimes but these were an instant hit. The sizing was great and fit as expected, with plenty of room to wiggle toes. Highly recommend.
