Hi there! :) Definitely no likey $400! (Here are the Loeffler Randall shoes if anyone else wants to see.)
One of the closest matches I found is Madden Girl’s “Isobel” sandal (love the name, heh) for $35 (from $50). They are available on 6PM and on DSW (for $40). They’re also on Zappos for $40.
Another awesome option is Tahari’s “Gigi” sandal ($81). They’re a little more streamlined but they are a similar gray color and have that chunky heel.
Here are two more options that are similar in look and feel: these Nine West sandals (about $75) and these suede sandals from Sole Society ($69.95).
