My son has been wearing these boots almost daily for a few weeks.  He loves them.  We also have the matching raincoat.  They are boots; they are fine. Seem like they will last at least until he outgrows them, and if so, they will be handed down to his brother.  The design is very cute, he can put them on by himself (he is 3), and I assume they are comfy, or he wouldn't wear them. I gave them 4 stars because I am not jumping up and down with excitement over them; once again, they are just boots. Not expecting to be wowed here.

Update (7 months later): My son still loves these boots, and he has worn them frequently. However, They have multiple cracks in them, most of which go all the way through, so they no longer keep out water. In fact, the entire front of both boots now lifts up so you can see his foot. My other son has Hatley boots, which have received just as much wear as these, but still look new and have no damage or wear at all. I woudn't recommend these if you want them to function as rain boots. Hatley is much higher quality.
