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!
