Also available in red and papaya here
I ended up getting both the black and nude pair at Nordstrom, because I earn rewards there and I had Notes to spend. I couldn't decide if I also wanted the red and/or papaya, but I decided I needed the two neutral colors for now. They are a bit pricey for what they are but, seeing as how hard it was for me to find them, I snapped these up without a second thought before they sold out.

There are some marked differences, such as the raffia wedge and boxier shape. Also, the toe are is a bit more squared-off compared to the Via Spiga, which are round. And is it just me, or is the patent a bit more muted in the L.K. Bennett pair? All in all, the Via Spiga's are a good interpretation.
