Lauren by Ralph Lauren's "Carsyn" espadrille wedge sandals are $79 at Macys.com.
Get the look for less with Chinese Laundry's "Dilly-Dally" instead, available in four colors on sale for $29.99–44.21 at Endless.com. I have a similar style wedge from Kohl's and they are seriously comfortable yet will give you that height you need with walking shorts and summer dresses.
