I admit I was heartbroken when I went to Target and learned that the Hunter boots for toddlers had sold out within an hour of stocking. Well. . . thank goodness they were! These Crocs boots are absolutely perfect.

Pros:
 - incredibly light-weight.
 - remarkable grip. I can seriously attest to this - I have probably the fastest moving, most accident-prone little 3 year old on the planet. Shoes that don't grip are a deal-breaker for us because we definitely can't lose any more brain cells to concussions. And these boots have great grip for him - no spills! We also bought these in a size for him to grow into, with no loss of traction. Huge plus!
 - Color - a little darker than advertised, but a nice dark blue.
 - Ease of use: My 3 year-old has no trouble pulling these boots on himself and taking them off. No need to jam the little toes into this boot or stomp around the house. They slip on, and then (somehow, magically) stay on!
 - Easy to clean: just hose them off and let them dry!

Cons:
 - zero. they are incredible.

Pro Tip: If your kid is about to outgrow the size down, you can easily size up in these for maximum wearing and no issues with grip or real issues with fit. Even with room in the toe, we've had no issues with these.

Pro Tip: for maximum puddle fun, we found a pair of water-proof "splash pants" (https://www.amazon.com/dp/B017YC1MK8/ref=cm_cr_ryp_prd_ttl_sol_1) that we love. We let him get all kinds of muddy and then toss the pants into the wash. It's awesome.

Haven't tried these in the winter, but I bet with a thick sock or liner, these puppies would hold up nicely in the snow... More to come once we try it.
