Based on their sizing, we needed size 9.5, but bought size 10 because our son is growing so fast. They're tight - length, width, depth, all snug. These were more than I originally wanted to spend but thought it worth it if he had room to grow, but being so tight, he doesn't get to wear them for long. Disappointed.Cute shoes. But I ordered the 7.5 because my daughter's 7's are almost becoming too small. There is virtually no difference between the 7 and 7.5. Should have bought the 8.We tried several shoes for my grandsons thick feet. These worked great. Other shoes we couldn’t get his foot in. These are great for thicker feet.Adorable and Saucony always fit my kids huge feet.I cannot say enough good things about Saucony kids tennis shoes. They hold up to a lot of abuse and provide great support to my daughters growing and developing feet.I purchased this shoe because it’s listed on the Stride Rite website and I thought it would be a supportive option along then same line as Stride Rite brand. I didn’t have time to wait for shipping from their website so I ordered on Amazon for quicker delivery.The product is far from the quality that I expected for $45. The shoe seemed more like a $20 shoe that you’d by at Walmart. There is no arch support and the base of the shoe is completely flat. The only positive is that the shoe does seem light in weight but I believe that is because of the poor quality.Save your money.These seem to run extremely narrow. We re-ordered in XW and it was still too narrow for my son's wide feet! He loves the look of them, but I'm afraid his feet will hurt.My kid spends a lot of time outdoors with moderate mud exposure. Our clay mud does not wash out of these shoes. Otherwise they are fine, but its a toddler shoe. It should be wash and wear.The size says 4.5 xwUs. It says kids boys so I thought it was a boys size shoe. It was a toddler shoe. It was a nice cute shoe thoughWe wanted big kid's size, but we got infant size. The size is totally wrong.The shoes were super cute but very very small. The description is misleading and it is not good for 4-8 years, as mentioned in the description.smell came from it after a few times wearingEasy to get on and off. Good tread, but light weight.
