I recently got a shoe/pedal combo from pricepoint, Crankbrothers Acid Pedals (larger platform than the smarty/candys), and Sette Element MTB Shoes. The shoes run a bit wide (which is good for my feet, but maybe not for yours). I haven't tried riding on them with regular shoes, but I think they'd work out ok for that.
$99 + shipping (they went up $10 since I got mine)
How did they fit, I had some of their carbon road shoes and they were great, but never the MTB shoes. I have wide feet and the road shoes were perfect. I wish they had carbon mtb shoes
