Are motorcycle boots like dress shoes?

No, I don't mean awesomely stylish and made from fine grain leather from only the most kosher cows in the world.

I mean in terms of use and stretch.

I bought some Tourmaster Solution boots. Size 42. I used my dress shoes as the size reference and most of them are 42. All the shoes I buy fit like shit from the start, feet hurt, and are uncomfortable as hell. Then after 2 - 3 wears they are like butter because the leather stretches and forms to my foot.

I bought these in 42, my big toe is lacking maybe 2mm of space. Im also wearing gym socks, if I put on dress socks, im sure it will be better. But before I go that route or get a size b***** which might be to big, id like to ask.

Do motorcycle boots stretch and break in like dress shoes?
