Really like these boots
Bought these to help with Achilles heel problem, needed to have slip on winter boots that fit more like a shoe. I can put an arch support in it and still have a snug fitting boot that lets me slip in and out of. Pretty warm and comfortable in - 10 temps so far

Perfect for school
Bought these for my nearly 11 yo son who has outgrown kids sizes. He's worn Bogs boots for the past several winters and has never had an issue. Liked them because most men's boots have laces and wanted to avoid that due to frequent changing into "indoor shoes" at school.

Fast to put on, great waterprotection, hard to take out
Love the boot now, didn't like them at first, they hurt my feet on the first hour, but now they are fine. Super easy to put on, a little bit harder to take out, suitable when you need to go out fast and it snowy outside. great protection againts water.
