Dick's Sporting Goods takes up to 60% off a selection of men's clearance shoes. Shipping adds $5.99, although orders of $25 or more bag free shipping. (In-store pickup may be available for select items.) A couple of best bets with free shipping, assuming you pad the first item (these fish hooks are $1.29):
Converse Men's Chuck Taylor All Star Crimson Low-Top Casual Shoes for $24.97 (low by $5)
Nike Men's Free RN Flyknit Running Shoes for $69.97 in Multi or Black (pictured, low by $20)
