This brand was recommended by a family member as being good for kids who are learning how to walk, and I definitely agree. My son had a different pair of shoes from Carter’s that fit well and looked cute, but the soles were a little too slick for an early walker despite having little rubberized dots on them. I like that these have more realistic soles, with real traction and support, but still allow the kid’s foot to flex. My son is very comfortable in them and was immediately noticeably more stable while standing and practicing walking in them. Bonus- they are super cute and this design is neutral enough to go with plenty of his clothes. My only small complaint is a little thread coming loose on one shoe, but so far it isn’t causing any issues/doesn’t seem to be unraveling anything structural. Highly recommend overall!

Great shoes!

Size: 18-24 Months Toddler, Color: Grey Leather

Love these shoes, only shoes I put my 15 month old in. However, they do run small. I bought 12-18 month size and my boy out grew them before 12 months old, I had to repurchase 18-24m to fit perfectly.

The BEST toddler shoe!!

Size: 18-24 Months Toddler, Color: Brooks Grey Leather

These shoes are 100% worth every penny. They are super easy to get on and off due to the fact that the tongue pulls back fully and they are flexible yet sturdy. They are excellent quality and have maintained great condition with my busy toddler at the park. The wide toe box provides great comfort for my little one’s wide feet. Buy the shoes!!!

Bummed they fell apart they are super cute

Size: 12-18 Months Toddler, Color: Raiden Camel Suede, Size: 12-18 Months Toddler, Color: Raiden Camel Suede

I’m so bummed because these shoes are so cute and highly rated but mine fell apart after only a few wears. They say light outdoor activities and I would assume they mean walking up and down the block in the neighborhood. My son is only 15 months old and doesn’t walk fast or far at all so it’s really disappointing they fell apart.

Fall apart easy

Size: 12-18 Months Toddler, Color: Navy Leather, Size: 12-18 Months Toddler, Color: Navy Leather

Stay on, easy to put on, but get scuffed easily. Velcro strap came apart and color came off of leather about 2 months of wear
