Finding a flat that looks this good and feels this good used to mean choosing one or the other. A structured square toe, and bold hardware detailing that makes them look like they cost three times what you paid — paired with a cushioned footbed and flexible sole that make you forget you're on your feet.

Measure your foot from heel to longest toe and compare to the chart above. Between sizes? We recommend going up a size.
What makes the these flats worth it:
Comfortable upper. Premium material that shapes to your foot over time, gets more beautiful with wear, and tells the difference between a shoe built to last and one built to photograph well.
The structured square toe. Modern, deliberate, and effortlessly chic. The silhouette that fashion has been reaching back to because it simply works — elongating the leg, grounding the outfit, making everything you wear with it look more considered.
Bold hardware detail. That one piece of hardware that does more work than most accessories. It makes the Opium unmistakably intentional — the shoe in the room that people notice and ask about.
Cushioned footbed + flexible sole. Because elegance shouldn't cost you your comfort. The Opium moves with you — not against you — from morning errands to evening plans without a single thought about your feet.
