Shoes for oddly shaped feet I have somewhat oddly shaped feet; They're very wide and my big toe on either foot points slightly inwards. Shoes with pointed toes generally cause me a lot of pain, so finding a road shoe has been somewhat difficult.

Typically, I buy shoes that are slightly too big, and I'm wondering how this will affect cycling shoes. I'm looking at a leather pair that has an extra inch of room in the toe, and lacing them up very tightly seems to do the trick for now, but I'm worried they'll stretch with time and become too big to hug my foot tightly.

Has anybody had similar problems finding cycling shoes? Any recommendations for a wide-toed shoe, or some brand specifically known for conforming to your foot over time?
You should look at using mountain style Shimano SPD compatible shoes.  In general, mountain shoes have a little more room and give and there are a lot of brands that are SPD compatible. 

Keen has a line of cycling shoes and sandals that you can find at larger outdoor retailers like REI or many places online.  I mention REI specifically because in the past I have ordered two sizes of clothing and footwear online and returned the one that didn't fit with no hassle. 

My experience with Keen footwear is that the run a little wide all over and are especially wide in the toe box.
