I thought the rubbery sold would provide some shock absorbency, but it does not because the inside bottom of the shoe is incredibly hard - like walking barefoot on concrete. So I replaced the insole with a sports insole and it is still not enough because the bottom of the shoe is so hard. Sometimes I like to kick off my shoes under my desk when I am working, especially warm boots like these, but that cannot happen with these boots because getting them on or off is an entire project - and I have a slightly narrow foot. If I can manage to get them on, they are on for the day. I will never again buy boots without zippers.
