Great Fit for Wide Toes
Size: 5 Wide Big Kid, Color: Fuchsia
I should start by saying that these shoes were tested by an adult who happens to wear a child's size 5.5, ladies size 7.5 or 7W, and ordered a size 5W in the florescent pink. These shoes are way more comfortable than the other Saucony sneakers I own. The wide toe bed doesn't put any pressure on the outside of my feet and my pinky toes are loving the extra space. The insole is not removable in these shoes, but I found them to be comfortable enough without an extracurricular insole. I have only used these shoes for active days; running errands, doing chores, walking, but not for running or exercise. My adult feet and body found these shoes more suitable for walking, but for a younger person I would expect these to be great for exercise or daily wear. The color is super vibrant. I don't mind a bright shoe and I own a lot of colorful footwear, but these are shockingly pink. Then you combine that pink with the bright white sole, and it is borderline blinding. I have worn them a few times now and they definitely stand out. These would be a great option for a pink loving person, or someone looking for an eye catching shoe to punch up their wardrobe, but for me they're almost too much. These shoes are on par with my expectations for the brand, but I feel like they have an inflated price point, that most parents shopping for kids athletic shoes may struggle to justify. I know that finding shoes to accomidate wide feet can increase the price significantly, but I still think these shoes would be best purchased on sale.

Perfect girls tennis shoes
Size: 7 Wide Big Kid, Color: Fuchsia
These shoes have been great for my daughter! They’re lightweight, comfortable, and supportive enough for everyday running around, school, and sports activities. My daughter said they felt comfortable right away with no break in time needed. The bright pink color is really cute in person, and the shoes seem well made and durable so far. They fit true to size and have good cushioning without feeling bulky or heavy.

Stylish and comfortable
Size: 5 Wide Big Kid, Color: Fuchsia
I got these for my 9 year old who needed new sneakers. She loves all things pink and instantly loved the look of these shoes. They are extremely breathable which is great for running around and airing out those sweaty feet. The fact that they are wide is perfect for her as well; so many sneakers end up being narrow and confining. They fit great and look great and both mom and daughter are very happy with these!

Comfortable, durable, affordable...what more could you want? Lol
These fit well and were comfortable for my son...and they lasted until he outgrew them. That's saying a lot for a 9-10 year old boy. Lol. They are a great deal for active kids.
