Black shoes work well with navy, grey or black pants.
Brown shoes are best suited to tan, brown, beige, greens, other darker earth tones.
Burgundy shoes work well with khaki, lighter browns, blue and grey.
Tan shoes look great with lighter earth tones, blue, beige, lighter tan or white.
And in my personal opinon, the most suitable shoes for men out of work is sporty sports shoes. It can match up with almost every casual clothes. It is necessary that men should have pairs of these shoes in shoes cabinets. When buy them, keep cost in mind and search for good sales and discount web stores where you can buy name brand shoes for less. Here is a good online store: www.fulljordan.com. It collects all Jordan series, from the classic Jordan 1 to the newest Jordan 2010, in good quality but cheap price. It is worth visiting.
