I'm looking for some work shoes - specifically ones I can wear between seasons. When it's warm, I tend towards ballet pump styles and when it's cold, I wear boots. I'm a teacher and walk around a large school site/teach on my feet all day so comfort is important. No high heels but maybe a chunky heel if low. Preferably I'd like shoes that can be paired with skirts and tights as well as trousers. What should I go for? I've looked at loafers but can these be worn with skirts?
