Personally i like them. I find them really comfortable to wear and look fairly smart-ish. I rarely wear DMs these days as i can't be bothered to lace the bloody things. So monkey boots fit the bill for me, saying that i have been wearing them on and off since i was a child. Some people like to slate them, but i have worn them to daytime events before and no one has ever said anything to my face.
Each to their own i say.
My brothers say they used to wear them in the day casually as summer wear instead of normal boots.
