Beginner Walker
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.

First shoes that stay on and feel good on my toddler’s tiny feet! High quality. Easy to put on. I bought another pair one size up for her to grow into. Love these.

Cute, don’t stay on well
Size: 12-18 Months Toddler, Color: White Leather
I love these for the look, comfort, and flexibility for a new walker. Her teachers complain that they come off easily, which we did lose one because of this out and about. We graduated from these to similar ones from striderite.
