I wear a size 15 shoe, day to day. Can anyone recommend a good wide MTB shoe for biking? I don't plan on riding clipless any time soon, but that could change next week so I'd like to go ahead and prepare for that as well as getting something with a nice firm bottom on it. Right now I'm wearing Van's as my bike shoe and the sole isn't near rigid enough. I have a a pair of Shimano MTB shoes in a 49 but they are too narrow and cause numbness in the foot before I even get on the bike, so those are a no go...

TIA,
Jason
