I just received the pair I ordered. They were a bit difficult to zip up. I would suggest going up a size if you plan to wear thick socks with them. Today, I wore them to work with a pair of thin socks and they zipped up much easier. As I walked around my classroom and the building I did not have foot pain due to the well-cushioned insole. I plan to wear them in London on vacation and will put in my Abeo metatarsalgia inserts so I am happy this boot has a removable insole. For walking around during work, though, the insole it comes with is comfortable. It has an arch support that is helpful, it's not quite high enough for me but it worked fine today.
