I recently bought these boots and have worn them out (with jeans) a number of times. They are very comfortable and probably best all but a few of my sneakers in terms of comfort. So, my two part question is as follows: Are they too casual for dress attire? If not, will they look silly with slim(mer) pants, particuarly the buckle? The pants in the last picture are not yet altered. I would ideally like these to be taken in, whether or not I pair them with the boots. Thanks in advance for your comments!
