I ordered these Croc boots and a pair of Kamik Miranda boots to compare to. I really like the design the Crocs, they are rigid and hold their shape and don't collapse around the ankles like the Kamiks. I was able to get them on my legs but walking around is a little uncomfortable because they're pretty snug on my calfs (5'9 175lbs for reference). I like the material on the Crocs better than the Kamiks, it's got more of a plastic feel that doesn't attract dirt like the rubbery coating of the Kamiks. As you can see in the picture, they are a bulkier than the Kamics in the toe area, and do not have as extreme of a grip on the sole. Im sure the Croc's grip is suitable for walking on pavement, but I need to use these on a fishing boat. Other than that both brands are the same height and the same weight. The string on the Crocs is not functional, but it is super cute.  I'll probably return the Crocs though, just because of the fit. I would recommend for someone with slim calfs.
