Macy's offers the Nike Men's Flex 2016 RN Running Shoes in Black/Metallic for $39.98. Pad your order with a beauty item (they start at $4) to bag free shipping; otherwise, it adds $10.95. Excluding padding, that's tied with our mention from two weeks ago as the lowest price we've seen. (It's the best deal for any color now by $9.) They're available in sizes 10 to 13.

Update: It now includes free shipping with no need for padding.
