Seems like overkill unless you are really spending a lot of time off road. MX boots are stiff...really stiff....at least they should be. They are designed to protect the ankles from too much flex. When riding or racing MX you are constantly putting your foot down or out away for balance and traction which leaves the ankles vulnerable.
A good riding boot would provide protection plus allow you to walk around at your destinations. MX boots are very awkward to walk in.
