I've really enjoyed all the pics of the black shell and these nst lace ups especially stand out in part because they look almost gunmetal gray, even green.
Is that the light creating that effect or have you actually noticed a change in the color? I'm debating on whether or not to leave some shell shoes out in the sun..
I think the sunlight was creating that effect more than anything. I haven't put any polish on these shoes; it'll be interesting to see if any areas light up to more of a grey color.
