By the same rationale, you should oppose boat shoes since, when worn away from a boat, they "communicate status (you have a [boat] worth buying special shoes for)..." And jeans, since they communicate that you have a farm or ranch worth buying special pants for. God forbid you wear a polo coat since it communicates that you need warmth between chukkers.32, driving shoes have two characteristics that make them appropriate for the task - they're very thinly constructed so that your foot can pick up on any information telegraphed through the pedals AND they often have a rounded heel to facilitate pressing down on and switching pedals. All very ridiculous unless, as I mentioned, you're actually in a performance vehicle out on a track. Just as wading boots would be ridiculous on the streets. The STYLE of driving shoes, however, communicates status (you have a car worth buying special shoes for) just like driving gloves or (puke) a Ferrari jacket. I no longer care for such things as I now drive a Jeep - where the accessories run more along the lines of Aleve to reduce back pain and a bull horn to make yourself heard to other passengers.
If you want a comfortable and casual slip on shoe without the construction of a penny loafer or a boat shoe, tuxedo slippers or belgian shoes are far more appropriate for the boulevardier.
