Outstanding pairing! Excellent picture showing a great-looking use of that naval boot. Taste is individual, but this boot with bright, hard-to-match pants like those, all shades of grey, grey flannels and jeans are a great look.
Alden of Carmel recently issued some color 2 longwing bluchers that it had Alden make to commemorate an anniversary. Beautiful and fun casual dress shoes. There are a number of pictures posted on this thread from the last few months, as rydenfan indicated. I have never seen other make-ups although there may be some out there from the past. If you are interested, I would get in touch with Alden of Carmel to see what it may have.
I would not wear the medallion captoe blucher with jeans, but I absolutely agree with Repo that the medallion captoe is a great, great looking shoe and is a fine choice for suits and business casual and, becaise of its sleekness amd elegance, is a much better choice for use with suits and just as good, if not better, a choice for business casual, than the lwb. This all assumes a traditional wardrobe.
