To me, I think the standard is set at what the coach wears to games. For starters, OB rocks Cortez, so i say eff you to those in the anti-tennis shoes camp. BTW- lolz@boating shoes. This is a landlocked state and no one here really goes sailing, don't start telling me I need to wear attire not suited for where we're at. I'll wear some casual leather shoes, but that's about it. Purple kicks are awesome, doesn't matter what style.
Obviously we all cannot be held to OB standard to being impervious to high temperatures, so I will not be wearing a windbreaker and gray pants when it's 105 out. But he is always at least sporting a XXL polo. If I had a purple blazer that would be nice for the chilly games, but I'm not making that investment yet.
