HEELS in retail

Got these super awesome shoes yesterday and I'd like to wear them to work! My job is retail, but I work in a department that requires a slightly more upper casual dress code (so a step above t-shirts and running shoes, but jeans are ok and I still have to wear an apron/vest (I work at lowes for anyone in the states)). I'm a kitchens consultant, so I help customers redesign their kitchens, bathrooms, or entire houses.

Do you guys think it'd be ok to wear these?? Or should I just stay away from heels all together. From what I recall there's nothing in the dress code that says heels aren't permitted. Just as long as it's a closed toed shoe.
