Amazon takes 50% to 70% off a selection of men's, women's and kids' shoes. (Prices are as marked.) Plus, Prime members bag free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping starts around $5.) That's one of the strongest general discounts we've seen on shoes at Amazon, yielding a number of lows on popular brands such as adidas, New Balance, PUMA, Frye, Sketchers, and Cole Haan. Deal ends June 5.
