Is the Castaner Espadrille Loafer true to size?

Castaner espadrilles generally run close to standard European sizing, and this is a slip-on, so the instep fit matters more than length. Try your usual size first and size up only if you have a high instep or wide foot.

Can I wear it in the rain?

No. The jute sole and espadrille stitching absorb water and can weaken when wet. Keep it for dry days and dry pavement.

What is the heel like?

It has a low block heel, which gives a little lift and a stable base. It is not a flat shoe, but it is far lower than a dress heel.

What is the upper and lining made of?

The upper is leather and the lining is leather, with a rubber outsole under the jute sole. That makes it more structured than a canvas espadrille.

How does it compare with a classic penny loafer?

It is lighter and more casual than a leather-soled penny loafer, and the jute sole makes it a warm-weather shoe. A penny loafer is more formal and more weather-resistant.
