Children's winter boots should be easy to slip on and off and keep feet warm and dry - definitely easy to slip on, but for some reason the zip kept unzipping while I played in the snow. After a while it got so annoying that he put on his old shoes instead. Not sure why it happened but never seemed to be able to fix it. I think zip/velcro is good, just didn't work on them.

Warm and, as far as I can tell from my 7 year old, comfortable, very wide although the velcro doesn't seem like that much adjustable also i didn't realize that even the Red Spider "Boys" variant would include sequins on the front of the toe but they were needed for a trip and it was too late and the sequins are falling out too which is annoying is, even my son didn't want the sequins on boots. They also kept his feet warm and dry in the snow.
