Sandals

[don quixote]

I have a wide foot and formerly used MTB shoes (with SPD cleats). After a few hours, my feet would ache. Not anymore. I have recently switched to the Shimano sandals (SH-SD65S, reg $79 on sale at colorado cyclist.com for $55), and I a very pleased with them. The cleats are sold separately. I wear an 8 1/2 shoe, so had to decide between a size 41/42 or a 43/44. The smaller size was too snug. The larger size works just fine. Go here for more discussions about sandals:

Some riders love sandals and some don't...

Another answer for wide feet are the Sidi Mega sized shoes.  They are available in variously priced models.   I like the lower priced Bullet 2's since I am not a fan of sandals for riding and prefer a well fitting shoe with a good bit of mesh.

Lake also has wide sizes and more support than sandals. I rode sandals from western MT to Duluth with no problems but wear shoes more often when I want to ride hard.

After 10k miles+ in shoes, I'm thinking of going with combinations of Keen sandals and Sealskinz, wool, and Coolmax socks.  Shoes don't keep me dry in the rain or warm in the cold.
