The boots are pretty comfortable, except when you are not wearing long socks that extends above the top of the boots. I get some minor discomfort in that area because of the velcro and stiffness of the backing.
Walking is very easy in these boots and I could wear them under jeans or dress clothes and just head into work.
These boots get hot especially in 90 degrees F plus days. When I'm not riding I would unzip the back which gives it more room to breath.
