A shoe rarely appears on its own. Look at how its shape meets the hem of your trousers or the line of the rest of an outfit.
Try one small change
Compare a full-length hem with a slightly shorter one using clothes you already own. Notice how much of the shoe is visible and whether the proportions feel balanced to you.
Use color with intention
A tonal combination can keep the eye moving smoothly through an outfit. A contrasting shoe can become the focal point instead.
These are visual experiments, not rules. Choose something that feels comfortable for the activity and conditions of your day.
