I've had good experiences in the past with Rockport Dressports for office wear. Not using them currently for that; however, my current most commonly worn "less than formal" shoe when kilted is this wingtip steel-toed work shoe from Rockport:

Before you pigeon-hole these Wing Tips as office wear only, check out these safety features.

Steel toes offer protection from workplace spills, while the electrical hazard protection creates a shock-blocking wall around your dogs. All this in a sleek and snappy design that's just as ready for a wedding as it is for a warehouse!

Durable dress Shoes? Yes:

Sturdy leather uppers
Slip and oil-resistant blown rubber outsole for excellent traction
Electrical hazard protection meets ASTM standards for non-conductivity
Exceeds ASTM impact and compression standards... great crush-proof protection for your dawgs
ASTM F2413-05 M I / 75 / C / 75 EH compliant.
Each weighs approx. 24 ozs.
