Agree. I've tried some walkable, MTB shoes only - knew right away that regular road bike shoes are not for me. Still, prefer just plain clothes shoes. I commute for around 30 minutes, then spend at least 8 hours at work. And changing shoes is a hassle for me - prefer to just not worry about it. Simpler.
For recreational rides, I LOVE SPD clipless shoes and pedals. But for commuting, platforms with studs are more than good enough.
