WHAT: CitySlips shoes for travelers.
HOW THEY WORK: These are packable ballet flats that fold in half and slide into a coordinating pouch that's compact enough to tuck inside a handbag or other small carry-on. The pouch unzips into a tote for whatever shoes you're transitioning out of while on the go.
HIGH POINTS: Fashionable finishes (metallics, snake and leopard print) can convert a tourist ensemble into dining attire or provide refuge from killer heels for the walk back to a hotel along cobblestone streets. A scrunchy back grips the heel. Rubber bottoms provide a modicum of shock-absorption. They're easy to slip on quickly in a cab, train or vestibule. As a more versatile, slightly hardier upgrade from flip-flops, these earn their place in the bags of busy women on the road.
LOW POINTS: Sizing is generic (a medium is 7 to 81/2, etc.), and I can't tell the left from the right. However I place them, the toe bed doesn't conform sleekly to feet. A bit of glue or something nudges both of my big toes at rest. Once I start walking, this isn't an issue. Typical of ballet flats, there is no arch support. The shoes aren't ergonomic enough to pound miles of pavement at a stretch, especially with sweat-inducing synthetic uppers.
