Is the Sai comfortable for all-day wear?

It is a wedge sandal with a leather lining and a rubber outsole, so it is more forgiving than a stiletto. The jute wedge is firm, though, and there is no cushioning described beyond the leather footbed, so long walking days are a stretch.

Can I wear it to a wedding?

Yes. The braided jute wedge and tan leather read dressy enough for daytime and garden weddings, and the wedge is steadier on grass than a thin heel. It is less formal than a strappy heel for evening events.

How does it compare with a classic rope espadrille?

The Sai adds a rubber outsole and a leather lining to the espadrille formula. That makes it more durable and grippier than flat rope-soled styles, at the cost of some of their light, barefoot feel.

What is the heel like?

It is a wedge, so the height runs continuously from heel to toe rather than sitting on a thin post. That spreads weight across the foot and makes it easier to balance than a slim heel.

How should I care for the jute and leather?

Keep the jute wedge dry; water softens and stains it. Wipe the leather upper with a soft cloth and use leather conditioner sparingly, and store the sandals away from damp.
