Macy's offers the Under Armour Men's Micro G Assert 6 Running Shoes in Black for $39.98. Pad your order with a beauty item (they start at $3) to bag free shipping; otherwise, shipping adds $10.95. (Amazon has them in select sizes for the same price.) That's the lowest price we could find by $5, although we saw them for $5 less in August. They're available in sizes 8 to 13.
