The famous Golden Triangle of Paris is on the Right Bank, just off the Champs Elysées, but the lesser known, much more important golden triangle of shoes is on the Left Bank, beginning as the corner of the rue d'Assas and the rue du Cherche Midi.
The first few shoes stores are local designers, or multi-brand boutiques as you walk towards the Carrefour de la Croix Rouge. You'll find shoes of every style, for every budget. As you get to the top of the street Robert Clergerie has a boutique, then there is a Camper store.
At the larger Centure statue, turn left to the rue de Grenelle towards the boul de Raspail and you'll be passing all the greats; Michel Perry, Marc Jacobs, Giuseppi Zanotti, Sergio Rossi, Prada, YSL, and even Christian Louboutin.
If that is not enough and you're still feeling like Cinderella after the ball, cross the boul Raspail and go to the shoe department at Le Bon Marché Department store for an over view of the world's most luxurious shoe selection.
