A best bet is the DieHard Men's SureTrack 8" Work Boots in Brown (pictured) for $79.99 before the above coupon, $69.99 after. With free shipping, that's $30 off list and the lowest total price we could find for this style. They're available in medium and wide sizes from 6 to 13.
Update: Spending more than $70? Instead use coupon code "SEARSSEPT" to cut an additional 15% off. That reduces the DieHard Boots above to $67.99.
