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.

Perfect for beginners. Size is relative. Be sure to measure your baby’s feet. Kinda pricey but so cute. Well made and durable for my 11 month old Granddaughter. Love the denim look and the wide toe box and flexible sole.
