Not sure about the numb foot problem, as I've been lucky and never had to deal with that problem. Certainly, you could try moving your cleat a bit. As for the saddle, unless you know the bike fits correctly, its really hard to determine whether or not the saddle is going to be comfortable. Could you go back to the bike shop and demand a proper fitting? You paid good money for that bike they sold you....... I think it is their absolute responsibility to ensure that it fits you as well as possible. If they aren't willing to do that, is there another shop anywhere nearby that you could try?
