I have more slip-ons than I know what to do with, but I have a REALLY high instep and I'm interested in one or more oxford or derby from Bennies' Grenson sale. My size is 8.5. I already have a pair of black captoes and chili captoes that are leather and deerskin. I wear a suit about 15% of the time but my everyday clothes at work are nice slacks, shirt with buttons and occassionally a sportcoat. I'm open to suggestions. Thanks in advance for your input.
