Opium | Comfortable Square-Toe Flats – Cushioned Footbed, Flexible Sole

Pretty flats that rub and pinch by lunchtime?

So many smart flats look lovely in the shop, but leave you with sore heels and aching feet after an afternoon in town. Hard, flat soles and stiff uppers mean you end up choosing between shoes that feel comfortable and shoes you'd actually want to be seen in.

Meet Opium: elegant square-toe flats made for all-day comfort

Opium is a women's square-toe flat with a soft, supple upper, a cushioned footbed and a flexible sole that moves with your foot instead of fighting it. The structured square toe gives a clean, modern look that works with trousers, jeans or a dress.
