I am applying as well in the fall. I own walnut Strands and would never wear them to a residency interview. They're significantly flashy and I wouldn't want PDs to remember me as "the guy with the shoes." I actually just ordered the black Carlyle for this very purpose. I would, however, wear the Strands to the pre-interview dinner if there was one, and I do wear them around the wards pretty often.
Dang :/ I love them, but can only afford one new pair of shoes at the moment.
I don't want black shoes, maybe I'll go with the brown strands.
