Great shoe!
Size: 5.5 Big Kid, Color: (106) Castlerock/Anthracite/Phoenix Fire
Great fit, very durable, excellent foot support, lots of great colors to choose from. We have had these for over 6 months and thy have not overstretched or come apart in any way. I am really pleased with these shoes for my child who is VERY hard on shoes and usually has sensory issues surrounding shoe comfort/tightness.

Great fit for kids
Size: 10 Toddler, Color: Light Grey
We purchased the RUNSIDE Boys Girls Tennis Shoes for my child and have been really happy with them. They’re super lightweight and breathable, which is great for all-day wear and running around. My child says they’re comfortable, easy to put on, and don’t make their feet hot. The shoes seem durable so far and have held up well with playground time, sports, and everyday use. They also look cute and match with a lot of outfits. The fit was true to size and the non-slip sole gives good traction. Overall, these are a great affordable option for active kids and I would definitely buy them again!

Shoe laces aren't great.
Size: 3 Big Kid, Color: Black White
I bought these RUNSIDE kids tennis shoes for everyday wear and school, and overall they’re lightweight, breathable, and comfortable for active use. My child liked how easy they were to put on, and they worked well for running and general play. The shoes themselves feel flexible and pretty comfortable for the price point. The upper material is breathable, which helps during sports or warmer weather, and they don’t feel heavy on the feet. However, the main issue is the original shoelaces. They constantly came untied no matter how they were tied, which became frustrating pretty quickly during the day. We ended up replacing them with better-quality laces, and that solved the problem. Pros: * Lightweight and comfortable for kids * Breathable material works well for active use * Easy for everyday wear and school * Good fit for the price Cons: * Original shoelaces do not stay tied well * Laces needed to be replaced for practical use Overall, these are solid budget-friendly kids’ sneakers that work well once the laces are swapped out. The shoe itself is comfortable and functional, but the included laces are definitely a weak point.
