I will keep buying these
Size: 3 Big Kid, Color: Black Orange, Size: 3 Big Kid, Color: Black Orange
This is the third time I have purchased these shoes. Every time my son grows out of them I buy the next size up. His favorite color is orange, so he loves the look of these. They are also soft mesh around the toes, which he loves so he can wiggle his toes. These are durable and well made. The pair i purchased before these is still wearable, just too small for him now. These are his daily shoes. The price has gone up since my first purchase, but they still are not unreasonable for how long they last. He is an active boy. He climbs trees, runs, and plays hard. So for any show to last 6 months when he wears them daily it shows the durability. It also shows that these shoes have tread on them thay stops him from slipping. He is able to move around freely and never has issues with grip. He puts them on without difficulty.

Comfortable, Durable, and Perfect for Active Kids
I recently purchased the Under Armour Kids' Grade School Assert 10 Sneakers for my child, and they are excellent! These sneakers are lightweight yet supportive, making them perfect for everyday wear, sports, and outdoor activities. The breathable mesh upper keeps feet cool, while the cushioned midsole provides comfort and shock absorption during running or play. The sneakers also have a durable rubber outsole that provides excellent traction, reducing the risk of slips during active play. The sleek design and modern style appeal to kids, and the shoes fit true to size, making them easy to wear for extended periods. Overall, the Assert 10 combines comfort, durability, and style, making it a reliable choice for active kids. They hold up well after repeated wear and are easy to clean, making them a great value for parents. Pros: Lightweight, breathable mesh upper Cushioned midsole for comfort and shock absorption Durable rubber outsole with good traction Sleek and modern design appealing to kids True-to-size fit and easy to clean Cons: Minimal color options in some sizes Laces may require supervision for younger children Overall: The Under Armour Kids' Grade School Assert 10 Sneakers are comfortable, durable, and stylish, perfect for active kids who need reliable everyday footwear. Highly recommended!

Great quality
Size: 5 Big Kid, Color: (105) Mod Gray/Black/High Vis Yellow
Only these sneakers could withstand the wear and tear of kids on the tennis courts. Excellent quality, sufficiently wide, and a great price.
