Sole separation
Size: 3 Big Kid, Color: Black/Orange, Size: 3 Big Kid, Color: Black/Orange
I really dont like to write reviews, let alone a negative one. Have had the shoe 1 month and the out sole on both shoes are peeling up. Normally we have had great success with saucony shoes for my boys. But this one we haven't had good luck. I have been super gluing the soles back down everything they peal up. Hopefully this is just a 1 off incident. Both side of one shoe and a large chunk of the heal on the other. You can see the glue marks and separation in pictures.

I ordered a kids size 1 for my child, and so far, I’ve been really happy with these shoes. Here’s what I like: ✅ Stylish design and comfortable fit. My daughter loves wearing these. ✅ They don’t show scuffs or scratches easily. ✅ The color is what I expected from the item pictures and it’s really cute. ✅ The Velcro straps make these easy to get off and put on. ✅ There’s a piece of Velcro on the tongue to help keep it in place. Really smart. ✅ The seams have not pulled apart and overall, these seem to be really well made. They have offered good support for my child’s feet, and a shoe that my child can put on by themselves is a win for me!
