For summer riding shoes I've been wearing Redback's for years. I'm on my second pair. I have the black without the extra toe protection. They are waterproof, they are super lightweight, they breath really well, they are super grippy even on wet tile and really built to last.
I learned about them from a buddy of mine that owns a towing company and is really hard on shoes but needed something lightweight and non slip to walk on the roll back deck on his truck, especially when wet and slippery. I also noticed that several of the tech's at work (we used to call them mechanics) were wearing them around the oil, grease and coolant, and they are on their feet all day, every day, they said that the MAC tool guy carried them on his truck. I get mine from Whistle Work Wear.
