I bought my son's first pair of these shoes at Cracker Barrel; I loved them so much, I've bought two more pairs in larger sizes as he's outgrown them.  The soles are completely skid resistant, and have held up well to lots of walking outdoors.  They're very stretchy and soft - easy to flex with tiny baby feet, and easy to put on wiggly toddlers. They stay on very well.  The only time I've had an issue keeping these on my son's feet is when he's about to outgrow a size.  When I buy him a larger size, they stay on well again.

If I had any complaint, it would be that the top is made of a sock-like material, so when my son rubs the bumpy bottom of one Skidder on the top of the other, the fabric pulls and pills.  For me, it's not enough to choose any other shoe, but it's not ideal.
