I recently picked up a pair of these:
Drew's Roughout Lace to toe for Wildland Fire use. Just got them Thursday, got started breaking them in Saturday, and fought fire in them all day Sunday. Yes, they are absolutely Hideous, but they work well for their intended purpose. The heels make quite a bit of difference on any kind of incline, and the Vibram soles are double stitched and screwed on so they aren't coming off. They were pricey, but I should get a lot of use out of them. They look a lot better (to me anyway) now that they are scratched up a bit, and covered in ash and dust.
Take care all
