The following images were taken from a photo that I took of a group of men and women who I went on a motorcycle ride with recently. These guys ride regularly and belong to the same group that I do. We ride together often (as often as my schedule permits, anyway.)
This proves beyond doubt that real bikers wear boots. See any sneakers? No? End of story.
Life is short: wear motorcycle boots when you operate a motorcycle.
What boots did I wear? I wore my Wesco combat boots for a little different style. Too bad the leather BDUs inflated with air and look kinda puffy. But the BDUs bloused into the boots looked and felt great while riding.
