We buy only Kamik for our daughter.  We live on a farm and hike quite a bit so we have gone through quite a few boots.  Initially, I tried Melissa and Doug brand - CHEAP CHEAP CHEAP!

This brand is so much better.  I love the rain boots far better but these were nice to have for the winter as last winter my daughter's toes froze in the rain boots.  The only problem is that they are a bit more clunky.  I also wish that they were easily used as rain boots with the liner removed.  They soles have holes which makes them uncomfortable to use without the liners.  Shame on you Kamik!  For the price we pay, we should be able to use these as two in one.

Otherwise, I love this brand and have tried a lot of them.  For adults, I recommend the Sloggers boots.
