I am newly into riding to and from work and decided to purchase these.  The are very comfortable in general wear and while riding.  I do not find that I get any chafing or slip while riding.  I get slight numbing/cramping in the front arch/toes but have had that with runners and basketball shoes as well so it is a me thing and merely requires a slight adjustment to how tight the shoe is.  Being that the shoe has velcro straps it is easier to adjust for this as I can independantly adjust the tension on the fore foot, mid foot , and around the ankle.  In runners and basketball shoes with standatd laces the lace shifts allowing the tension in different areas to equalise even if you don't want it too.  Have had one spill(chain snapped) and shoes still look near new.  Only thing I would change is that the tread would make you think you can walk in these and you can no doubt about it.  But the cleats crunch and click alone where you go so you are wearing out the cleat (or the floor) and it would be nice to have a cover of some sort or have the cleat slightly more recessed.  I don't know enough about biking to know if the recessing is possible and have seen online the covers though have not ordered them myself as these are biking shoes and i am required to do little walking when wearing them.  More pointing it out in case you think you will be walking in them.
