First decide what type of riding you intend to do. If you are mostly doing day rides where you are back at home everyday things like cold feet, wet feet, sore feet, etc., will be of less importance to you. When you get home you can change your footwear and all is right with the world again. If you plan on doing multi-day or multi-week motorcycle tours you do not want to do the whole trip with wet, cold feet, sore feet. While deciding that however, keep in mind that you are more likely to have an accident close to home so don't disregard the need for proper protection in whatever footwear you decide upon.
I suffered through wet cold feet and/or the frustrating hassle of trying to put rubber boot covers on while standing on the side of the road for to many years before I smartened up and bought water-proof boots that that allow me to just keep going when the sky opens up. I bought motorcycle specific boots because they provide the required protection in the required places, keep my feet warm when it is cold, keep my feet cool when it is hot, keep my feet dry when it is raining, they don't slip on the asphalt causing me to drop the bike, and they are flexible and comfortable enough to walk around in when I stop somewhere to sight-see. I bought them to use when I am motorcycling and I only wear them when I am motorcycling. Because of this they have lasted very well. When I bought them they were expensive relative to non-motorcycle boots but they provide advantages over regular boots that are not designed for motorcycling that I consider beneficial. I bought them way back in 1998 or 1999 and I am still wearing them. While they are beginning to show their age and I can see new boots in my not to distant future they still do all of the above mentioned things well and I am still wearing them. Even without factoring in the advantages that they offer, amortized over the 27 or 28 years of use that they have already provided to me plus whatever number of additional years that I might continue to wear them, the amount that they initially cost over and above the price of regular boots has become irrelevant to me.
