Cute shoes for new walkers
Great shoes for new walkers, with a sturdy heel cup and flexible sole, and super easy to get on/take off. The fit is a bit on the narrow side, so recommend checking the size chart. Great colors too! We've bought multiple pairs in different sizes and have always been happy.

Great shoe: 5th pair purchased!
I love these shoes! They fit true to size and never wear out. Both of my girls have worn these exclusively from 9 months through kindergarten. My oldest just learned to tie laces and that’s the only reason I’m moving her on to different shoes. These are stylish and they grow out of them before the tread even begins to show wear. Additionally, unlike cheap sneakers from Walmart or Target the Velcro holds strong despite a year of use by two different children.

Great purchase!
My child is 14 months and has been on the move for a long time, these shoes are so great, he moves great in them and never has a problem wearing them!
They are slightly narrow so the strap doesn’t go all the way, but has never come undone!

Worth every penny
My son’s favorite shoes! High quality, very durable, look nice even when they aren’t freshly cleaned. Easy to take on and off. Definitely worth the money! This color tends to go with everything. Such great support.

Nice looking shoes, Saucony is always very durable for my child and myself. Very comfortable and fit perfectly. Great for just hanging out or running.
