Repetto's classic ballet flats are known for their soft leather and flattering low profile. The pair shown here is $250 at Saks Fifth Avenue.
Gap has been carrying these genuine leather ballet flats for a couple seasons now and they are the best Repetto-inspired shoes I've seen on a budget. I own a pair and they are amazingly comfortable, especially after I added some gel insoles. Plus, they have that perfect ballet-flat look that's so hard to find. Get them for $39.95 in black, bronze, metallic silver or blue at Gap.com.
