+1 to some MTB shoes, although if you've got toe-cages on the pedals, either take a pedal with you shopping or just try to pick out something with a low enough toe profile to easily fit. Your shoe size might not have as much of a problem with that as my 13's, but its something to consider.
I started riding MTB shoes, then clipless, then after a year of that, finally went to road shoes.
Riding crank bro's pedals, I'm still re-learning how to plant that cleat right on the egg-beaters to clip in since I don't have the "guide" formed by the tread on the soles of my mtb shoes.
