I use Bates. The are designed for military, police, and other security types, are more solidly built than running shoes, are built without the slightest metal (so you don't have to take them off at airports. The have a high volume toe, so they are not pretty, Bates sells them as "tactical" which usually means Black Nylon, or something similar.

I added elastic laces from Lacelock, so I don't have to retie them or tangle the laces around a pedal or tangle in the chain ring, and I use plain, block pedals. Very comfortable., low tech. I like the look of Adidas Sambas, but I don't care for suede, I want full grain leather. Black, green?
